The effect of heat on the body

Heat can cause the body expands, becomes a liquid or into a gas. Eg metals expand when heated. Ice melts when heated, water evaporates when heated. Heat is also called heat. Heat can not be seen by the eye. Heat is also a form of energy, ie heat energy. If an object is to release heat to another object, the heat received by other object is equal to the heat that is released it. The heat affects the body either solid, liquid or gas. Heat can cause changes in temporary and permanent changes. In general, all objects expand when heated. All solids when heated continuously into melt, melt or fuse. The water is heated constantly changing into water vapor. The liquid turns into gas objects through evaporation. When things cooled gas instantly transformed into a solid object which is said to undergo sublimation.
