mention the effects of heat
Answers
Answer:
The following are the effects of heating
1) 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
2) Increase in temperature:
When heated there is an increase in kinetic energy and particles move at a higher speed. Since temperature is a measure of average Kinetic Energy, the temperature increases.
3) Change in the state:
When there is a phase change of solid to liquid and liquid to gas, the temperature remains constant but there is absorbing of heat, heat absorbed is used to separate particles and there is no rise in temperature.

Prolonged exposure to extreme heat can cause heat exhaustion, heat cramps, heat stroke, and death, as well as exacerbate preexisting chronic conditions, such as various respiratory, cerebral, and cardiovascular diseases.
