| Answer» Whilekinetic energyis theenergywhich an object contains because of a particular motion. On the other hand,potential energyis the storedenergy, because of its state of rest.Role of latent heat in state of change of substance :Latent heatdoes not raise the temperature.But thelatent heat has always to be supplied to changethestate of a substance.It is calledlatent heat because it becomes hidden in the substanceundergoing thechange of state,and does not show its presence by raising the temperature. | |
