Relationship between temperature, heat & thermal






Temperature is a measure of the average kinetic every of the particles in the sample of matter. All the particles in a matter are moving at different speeds. The faster the average movement of the particles = a higher average temperature.






Heat is the energy that flows from something with a higher temperature to something with a lower temperature. It is also measured in Joules(J)




Thermal Energy is the total energy of the particles that make up a material. To find thermal energy you add all the sums of energy(potential&kinetic energy) to find thermal energy. It also depends on:



1.Mass

2.Type of substance

3.Temperature


So the faster an object moves, the more kinetic energy it has.



Ex) a ball rolling

a ball sitting



ALWAYS from a WARMER object to a COOLER object


And a thermal insulator is something that doesn't allow heat to flow through it easily. Such as a thermos bottle to keep your hot drink warm. The thermos keeps the warm air inside instead of escaping.

So, they are all different but; temperature is the average measure of the energy. Thermal energy is thetotal energy of the particles, and heat is the flow of the energy from something with a higher temperature to something with a lower temperature.
