Energy {heat, energy}| {thermal energy} can be total random translational kinetic energy and total potential energy, in all directions, that holds atoms apart. Heat as kinetic energy raises temperature. Heat as potential energy makes solid into liquid and liquid into gas.
work
Heat energy has no direction. Heat energy in solids or liquids can do no work.
kinetic energy
Heat translational kinetic energy equals number of molecules times temperature.
potential energy
Solids have little heat potential energy. Liquids have some heat potential energy. Gases have much heat potential energy.
