how are expansion of matter
Answers
Answer:
Thermal expansion is the tendency of matter to change its shape, area, and volume in response to a change in temperature. ... The relative expansion (also called strain) divided by the change in temperature is called the material's coefficient of thermal expansion and generally varies with temperature.
Answer:
All the three States of matter ( solid, liquid, gas ) expand on heating. On heating a solid, the particles gain energy and vibrate more vigorously about their respective fixed positions, forcing each other further apart. This results in the expansion of a solid. Similarly , the particles in liquid or gas on gaining energy are forced further apart causing expansion. The degree of expansion depends on the substance. A liquid on heating will expand more than a solid. Gases expand enormously when heated.
