Question
A quantity of heat requirad to change the unit mass of a solid substance to its liquid state, while the temperature remains constant, is known as
Options
A.ltent heat
B.ltent heat of fusion
C.heat
D.specific heat
Solution
During fusion of solid into liquid some energy is used up to transform the state of matter from solid to liquid. Since it does not increases the kinetic energy of particles, there is no increases in the temperature of the material. so phase transformation takes place at constant temperature.
