physics heat test
what is heat
heat is a form of energy that can be transferred from one object to another
what is heat measured in
joules
what does temperature measure
the average kinetic energy
whats the difference between temperature and heat
heat is energy, whilst temperature is the measure of that energy
what happens when you heat gas
the particles soread out more and move faster, causing the pressure of the container to rise
whats equilibrium
two objects or substances reach the same temperature, so there is no net transfer of heat between them
why does temperature increase along a thermal conducotr
conductors allow heat to move easily through them. This happens as particles in the conductor vibrate and pass energy to their neighbouring particles, creating a rapid transfer of heat.
How does temperature increase along a thermal insulator
temperature increases slowly because insulators don’t let heat pass through them easily. The particles in an insulator don’t pass energy on well to neighbouring particles, so heat moves slowly through the material.
