Question

Explain affects change caused by heating

Answer 1

Explanation:

When heat is added to a solid, the particles gain energy and vibrate more vigorously about their fixed positions, forcing each other further apart. As a result expansion takes place. Similarly, the particles in a liquid or gas gain energy and are forced further apart. The degree of expansion depends on the substance.

Answer 2

Answer:

Following are the effects of heating

• Expansion: When heat is added to any substance, the particles gain energy and vibrates(with more speed) or vigorously about their fixed positions, forcing each other further apart.
• Order of expansion Gas>Liquid>Solid
• Increase in temperature: When heated there is increase in kinetic energy and particles move at higher speed. Since temperature is a measure of average Kinetic Energy, the temperature increases.
• Change in state: When there is phase change of solid to liquid and liquid to gas, temperature remains constant but there is absorbing of heat, heat absorbed is used to separate particles and there is no rise in temperature.
