What expands the most when heated?
Thus, the gas expands the most on heating and solid expands the least.
Thus, the thermal expansion is highest in gases, then liquids, then solids.
- nitrogen – 1 to 696.
- liquid helium – 1 to 745.
- argon – 1 to 842.
- liquid hydrogen – 1 to 850.
- liquid oxygen – 1 to 860.
- neon – Neon has the highest expansion ratio with 1 to 1445.
Answer :Gas. explanation: Gases expand much more than the liquids and the solids. The greater the attraction between the molecules, the smaller the expansion will be.
The higher the attraction between the molecules, the higher will be its expansion. As this attraction is the most in solids and the least in gases, solids expand the least and gases expand the most on being heated.
Liquids expand for the same reason, but because the bonds between separate molecules are usually less tight they expand more than solids. This is the principle behind liquid-in-glass thermometers.
Gases expand the most upon heating because the intermolecular space is more than in solids or liquids.
Gases expand much more than the liquids and the solids.
Out of solids, liquids and gases, gases expand the most.
Answer :Gas. explanation: Gases expand much more than the liquids and the solids. The greater the attraction between the molecules, the smaller the expansion will be.
What substance can make it expand?
Two examples are water and air since their density decreases and volume increases and hence expansion takes place. The main reason for expansion on heating is, when we give heat to material particles in the material get excited about taking energy because heat will work as energy.
Almost all materials (solids, liquids, and gases) expand when they are heated, and contract when they are cooled.

So comparing with liquids, solids expands less on heating & liquid expands more.
Is Water The Only Substance That Expands When It Freezes? No, it is not. Other such substances include plutonium, germanium, bismuth, gallium, silicon, acetic acid, etc.
Hydromorphic Polymers. These are polymers that expand and contract on contact with water. This smart material is sometimes used in toys that can expand up to five times their original size, such as bath toys.
All three states of matter (solid, liquid and gas) expand when heated. The atoms themselves do not expand, but the volume they take up does. When a solid is heated, its atoms vibrate faster about their fixed points.
The liquid which expands minimum on heating are Mercury and alcohol.
Just about every (but not all) solids expand with an increase in temperature.
Solution : From the three states of matter, solids expand the least.
Solids expand the least and gases expand the most when heated because this attraction is greatest in solids and least in gases.
What expands more hollow or solid?
Solid sphere will expand more than the hollow one.
Thermoplastics expand considerably more than metals (e.g. Carbon Steel 10.8x10-6 compared to UHMWPE 200x10-6 i.e. approximately 18 times more). Linear thermal expansion means the product will expand in all directions and this needs to be allowed for in design calculations.
Wood has much lower coefficient of thermal expansion, So it is clear that aluminium expands more than steel and wood does.
The thermal expansion coefficient of metal is larger than that of glass. In layman's terms, this is the problem statement that metal expands more than glass when both are heated.
Gases expand more than solids.
Gases are in rapid motion, and they undergo elastic collisions with each other and the walls of the container; that is, momentum and energy is transfered not lost during collisions. Gases expand spontaneously to fill any container (rapid motion).
The reason is, that the particles of air or gas, far from being under the influence of cohesive attraction, like solids or liquids, are actuated by a powerful repulsion for each other. The addition of heat mightily enhances this repulsive tendency, and causes great dilatation.
Explanation: The greater the attraction between the molecules, the smaller the expansion will be. Solids expand the least and gases expand the most when heated because the molecular attraction is greatest in solids and least in gases.
As molecules in liquids are less tightly packed so they expand more than solids on heating.
Gas is the state of matter that expands to fill its container. Gaseous particles have very high levels of kinetic energy. They are also separated by large distances and they are thus relatively easy to compress compared to solids and liquids.
Which expands hot or cold?
Most matter expands when heated and contracts when cooled, a principle called thermal expansion. The average kinetic energy of the particles increases when matter is heated and this increase in motion increases the average distance between its atoms.
This occurs because of the unusual polymer structure of rubber. When the long chains get hotter and vibrate, they actually shorten, causing the material to contract. When the chains cool down, they relax and stretch out, causing the material to expand.
Invar, also known as FeNi36, is an iron-nickel alloy notable for its lack of expansion or contraction with temperature changes.
Aluminum expands much more than steel, when heated. Freezing witll contract the aluminum only to hold the broken race tighter? Try a heat gun or a torch or an iron or something to heat the aluminum . The aluminum will expand (3X) whle the steel will less (2x) and the bearing should come out.
As water freezes it expands. So, ice has more volume (it takes up more space, but has less density) than water. Share with the children that this is a very special property of water.
Metal expands when heated. Length, surface area and volume will increase with temperature. The scientific term for this is thermal expansion. The degree of thermal expansion varies with different types of metal.
If equal volumes of water and alcohol are heated to the same rise of temperature, then alcohol will expand more than water because coefficient of real expansion of alcohol is more than that of water.
Solids expand the least and gases expand the most on being heated.
When liquid water is cooled, it contracts like one would expect until a temperature of approximately 4 degrees Celsius is reached. After that, it expands slightly until it reaches the freezing point, and then when it freezes it expands by approximately 9%.
Is there any liquid other than water that expands when frozen? Other substances that expand on cooling are silicon, gallium, germanium, antimony, bismuth, plutonium, etc. More often, substances with tetrahedral structure exhibit this uncanny property.
What other than water expands when it freezes?
Other substances that expand on freezing are silicon, gallium, germanium, antimony, bismuth, plutonium and also chemical compounds that form spacious crystal lattices with tetrahedral coordination.
- Thermal expansion is defined as the tendency of a matter with an increase in temperature to change its shape, size and volume.
- When we increase the temperature of Aluminium it expands.
- Aluminium has the highest thermal expansion coefficient about 22 × 10 - 6 K - 1 .
Hygroscopic Materials
When that happens, the material changes by expanding in volume, becoming sticky, or otherwise altered. The list of hygroscopic materials is long. It includes paper, cotton, wood, nylon, polycarbonate, sugars, and many more. Not all materials are hygroscopic, however.
Ice is less dense than water, which is why it floats. When ice melts, the resulting water is denser, so a particular mass of what had been solid ice will have a smaller volume when it becomes liquid water. This change in volume exactly offsets the small percentage of ice that is above the water's surface.
Almost all the substances (solids,liquids and gases)expand on heating..
Iron, water expand on heating.
The expansion (or contraction) of any material is due to the kinetic energy of its atoms. When a material is heated, the increase in energy causes the atoms and molecules to move more and to take up more space— that is, to expand.
As noted in Chapter 4 of the USDA Forest Products Lab's Wood Handbook, “The thermal expansion coefficients of completely dry wood are positive in all directions; that is, wood expands on heating and contracts on cooling.” However, moisture fluctuations impact dimensional movement of the wood at the same time.
Most matter expands when heated and contracts when cooled, a principle called thermal expansion. The average kinetic energy of the particles increases when matter is heated and this increase in motion increases the average distance between its atoms.
Concrete, rocks, metal objects, glass, and other solids all expand when they are heated. They all expand for the same reason, too. Their molecules move faster and push each other farther apart. When solids cool, the molecules slow down.
What expands the most solid liquid or gas?
Gases expand much more than the liquids and the solids. Like liquids, the gases do not have a definite shape, so they also have only the cubical expansion.
No, different solids expand by a different amount for the same increase in temperature. Expansion depends upon the nature of the material.
Metal expands when heated. Length, surface area and volume will increase with temperature. The scientific term for this is thermal expansion. The degree of thermal expansion varies with different types of metal.
Water is one of the few exceptions to this behavior. When liquid water is cooled, it contracts like one would expect until a temperature of approximately 4 degrees Celsius is reached. After that, it expands slightly until it reaches the freezing point, and then when it freezes it expands by approximately 9%.
