Thermal Energy.
- Thermal Energy is the total potential and kinetic energy of all the particles in an object._
- Thermal Energy depends upon the mass, temperature, and phase of an object.
- So, what is temperature? Temperature is a measure of how hot or cold an object is compared to it's reference point.
Thermal Expansion and contraction.
-What is Thermal Expansion? It is the increase in value of a material due to a temperature increase.
-What is Thermal Contraction? It is a decrease in value of a material due to a temperature decrease.
-How does Thermal Expansion occur? Particles of matter tend to move further apart as the temperature increases.
-What is Thermal Contraction? It is a decrease in value of a material due to a temperature decrease.
-How does Thermal Expansion occur? Particles of matter tend to move further apart as the temperature increases.
