What are the uses of expansion and contraction?
Substances expand (increase in size) when they get warmer, and they contract (decrease in size) when they get cooler. This property can be useful.
In which process thermal expansion and contraction are used?
Thermal Expansion and Contraction. Materials expand or contract when subjected to changes in temperature. The expansion and contraction with changes in temperature occur regardless of the structure’s cross-sectional area. Concrete expands slightly as temperature rises and contracts as temperature falls.
What are the uses of thermal expansion?
Thermal Expansion – Real-life applications
- ENGINE COOLANT. Another example of thermal expansion on the part of a liquid can be found inside the car’s radiator.
- WATER.
- THE GAS LAWS.
- VOLUME GAS THERMOMETERS.
- JAR LIDS AND POWER LINES.
- EXPANSION JOINTS.
- MERCURY IN THERMOMETERS.
- THE BIMETALLIC STRIP IN THERMOSTATS.
What are some uses of thermal expansion?
The difference in expansion causes the bimetallic strip to bend when the temperature is changed. This movement has many common uses including: thermostats to control temperature, oven thermometers to measure temperature, and switches to regulate toasters.
What is thermal contraction?
Thermal contraction is a decrease in a material’s volume when its temperature decreases. As the temperature decreases, the average kinetic energy of the particles decreases and they slow down and get closer together thereby decreasing the volume of the material.
What are the applications of thermal expansion?
What is thermal expansion?
thermal expansion, the general increase in the volume of a material as its temperature is increased. If it is not isometric, there may be different expansion coefficients for different crystallographic directions, and the crystal will change shape as the temperature changes.
How is thermal expansion useful?

How does temperature affect the expansion and contraction of concrete?
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. The size of the concrete structure whether it is a bridge, a highway,…
What does area thermal expansion indicate?
Area thermal expansion indicates expansion in two dimensions. Let’s say you draw a square on a piece of paper. Then, around your original square, you draw another square with sides twice as long. If your smaller square expanded in two dimensions, it would end up looking like your second square.
What is an example of expansion in pipes?
The pipes through which hot or cold liquid or gas flow are after given bends so that they may expanded or contracts with out cracking . 2)Over head power lines and Telephone wire installed on poles expand during hot weather and contract in cold weather. Furthermore, what is the example of expansion? expansion.
