What is an example of expansion and contraction in solid liquid and gases? ›

Most common example of liquid is mercury in thermometer it expands when it's put in a patients mouth. Cracking of glass when boiled water is put in it,this is expansion in solids. Gaps between railway tracks because they expands in summers due to heat in atmosphere,this is expansion in gases.

Liquid water contracts when cooled, and you would expect that it continues to contract as it gets colder. When it hits freezing and turns into a solid, it expands. That's why water pipes may burst when the water inside freezes over. Ice takes up more space than liquid water.

1) Engines of motor vehicles run when gases expand. 2) When making steel rims for wheels. 3) When the screw-cap of a bottle cannot be opened.

Solids also undergo thermal expansion. Railroad tracks and bridges, for example, have expansion joints to allow them to freely expand and contract with temperature changes.

Placing bottle A into a basin of hot water will cause the air inside bottle A to gain heat and expand. Placing bottle B into a basin of cold water will cause the air inside bottle B to lose heat and contract, creating space within bottle B for some air to enter.

Thermal Expansion and Contraction. Materials expand or contract when subjected to changes in temperature. Most materials expand when they are heated, and contract when they are cooled. When free to deform, concrete will expand or contract due to fluctuations in temperature.

Most common example of liquid is mercury in thermometer it expands when it's put in a patients mouth. Cracking of glass when boiled water is put in it,this is expansion in solids. Gaps between railway tracks because they expands in summers due to heat in atmosphere,this is expansion in gases.

The expansion by heat in different lorms of matter, is exceedingly various. By being heated from 32 to 212 , 1000 cubic inches of iron become 1004 1000 " water " 1045 1000 " air " 1366 Gases are, therefore, more expansable by heat than matter in the other two conditions ot liquid and solid.

What is an example of expansion in science? ›

Think about a balloon. If you heat the air inside, the air molecules will move faster and occupy a greater volume. The balloon will expand to accommodate this change– this is an example of thermal expansion.

For example, when a balloon is inflated in a cool space, the inflation is partial while on heating, it comes to full size. In thermal expansion, which is the increase in body dimension due to the increase in the temperature. Gases expand more at ordinary temperature than solid and liquid.

The expansion we see when a liquid is heated without a container is known as true expansion. The expansion of liquid that is perceived without taking into account the expansion of the container is known as apparent expansion. A liquid's real expansion is always larger than its apparent expansion.

Solids contract the least while gases contract the most. Table lists some examples of contraction. If we hold a very hot glass tumbler under cold water, it cracks. This is because the outer surface of the glass comes in direct contact with cold water and contracts more as compared to the inner surface.

The same happens in all liquids and gases, driving natural heat transfer upwards in homes, oceans, and weather systems. Solids also undergo thermal expansion. Railroad tracks and bridges, for example, have expansion joints to allow them to freely expand and contract with temperature changes.
