Ideal gases
•
Since the internal energy of an ideal gas is regarded as being purely kinetic
•
The sum of the mean kinetic energies of all themolecules in a gas is the internal energy of the gas.
i dont understand this statement. how can the internal energy just be regarded as purely kinetic? and what is the last statement mean? thank you!

Kinetic energy in the moving molecules of the gas... higher temperature = higher mean speed of molecules.

how is it just ke though? how is there no pe?

That's the assumption you make when you say 'ideal gas'
