Paper 5 ­ Thermal phsyics

Temperature refers to energy that is supplied to an object. According to kinetic theory, this causes the particles in the object to move faster, increasing kinetic energy. In solids this would take the form of faster
vibrations, and in a gas, the particles would move…

The average kinetic energy is proportional to the absolute temperature of the gas.
1 < c2 > = 2
3 kT
2m


Where T is the temperature in Kelvin and k is the Boltzmann constant 1.38x1023 J K1. This equation proves that when the temperature is at absolute 0 there…
