Heat is the energy an object has because of the movement of its atoms and molecules. Heat depends on the size or type of object. For example, A 1000 watt light bulb will give off more heat as compare to 100 watt light bulb.
Temperature is not energy, but a measure of it. Temperature does not depend on the size or type of object. For example, the temperature of a small cup of boiling water is the same as the temperature of a large pot of boiling water.
