you can also see this with the heating curves. for example, when ice is melted into liquid water, there is a plateau where there is heat being added but the temperature remains constant. this means molecules are transferring energy faster, but there is not a significant increase in the how fast the molecules are moving to cause another phase change yet.
The heat of an object is the total energy of all the molecular motion inside that object. Temperature, on the other hand, is a measure of the average heat or thermal energy of the molecules in a substance.
Heat is the measurable unit of transferable energy, while temperature is just a measurement of how fast the molecules are moving (i.e. this supports the idea of how gaseous molecules move much faster than those of a solid.
