i. The heat energy required to change substance from one state to another at constant temperature is called as latent heat of substance. ii. When latent heat is given off, the bonding between atoms or molecules of a substance strengthens, causing trans
The state of matter can be changed by heating or cooling it or by changing the pressure conditions on it. When a material changes state, its molecules behave differently but don't break apart. Since they remain essentially the same, they don't form a different material but simply change the...
