Question

8. Thermal expansion of solids and fluids difference​

Answer 1

When a solid is heated, its atoms vibrate faster about their fixed points. The relative increase in the size of solids when heated is therefore small. ... Liquids expand for the same reason, but because the bonds between separate molecules are usually less tight they expand more than solids.

Answer 2

Define and describe thermal expansion.

Calculate the linear expansion of an object given its initial length, change in temperature, and coefficient of linear expansion.

Calculate the volume expansion of an object given its initial volume, change in temperature, and coefficient of volume expansion.

Calculate thermal stress on an object given its original volume, temperature change, volume change, and bulk modulus.
