Heat is often referred to as thermal energy. A body, item, or system is said to have more heat when its temperature is high. Temperature refers simply to how fast an items molecules are moving. So as an object increases in temperature, its amount of heat or thermal energy, goes up. Thus, heat is not a specific thing inandof itself, but more of a property.
