Heat is a form of energy. To say an object has heat is to say its particles have energy.

Particles with energy are more disordered and move faster. Thus a liquid generally has more heat than a solid because the particles in a liquid are less ordered and move faster. Similarly a gas has more heat than a liquid.

However the heat in an object is the sum of the energy of its particles. Therefore a very large amount of solid would have more heat than a very small amount of liquid.

Temperature a measure of heat, and tells you how fast the particels are moving.
