Why is the potential energy of a gas is more than a liquid and therefore the internal energy is greater in a?

Question

gas than in a liquid

so can u tell why the potential energy is greater than in a liquid and also what is internal enrgy

please a simple explanation

any help will bee appreciated

Answer 1

Internal energy is the sum of the total kinetic and potential energy of the particles.

In a gas all the particles are spread out more and the attractive forces have been overcome and therefore they have higher potential energy.
