PHYSICS 1030L LAB: Heat of Fusion
... In addition to changing the temperature of an object, heat flow can change an object from one state of matter into another. There are four basic states of matter: solid, liquid, gas, and plasma. If enough heat is added to an object, the object will change from one of these states to the other. While ...
