A body is placed in a certain airstream
When a body, by heat or cold moves from one state to another, we say that has changed state. In the case of water: when it's warm, ice melts and see if we heat liquid water that evaporates. The rest of the substances may change state if you change the conditions in which they occur. In addition to temperature, pressure also affects the state as are the chemicals.
If a solid is heated, there comes a time when it becomes liquid. This process is called fusion. The melting point is the temperature must reach a solid substance melts. Each substance has a characteristic melting point. For example, the melting point of pure water is 0 ° C at normal atmospheric pressure.
If we heat a liquid turns into gas. This process is called vaporization. When...
