Explanation The phase changes are physical changes that take place if matter changes energy states, but chemical bonds are not broken or formed. It occur at specific temperatures( melting point, boiling point, or sublimation point)while heat is being added to or removed from the material or substance but the temperature will not change. The temperature will change only when the phase has completed...
