Consider the following statements:1. Steam at 100°C and boiling water at 100°C contain same amount of heat.2. Latent heat of fusion of ice is equal to the latent heat of vaporisation of water.3. In air-conditioner, heat is extracted from the room air at the evaporator coils and is rejected out at the condenser coils. Which of these statements is/are correct?

In thermodynamics, heat is the thermal energy transferred between systems due to a temperature difference. In colloquial use, heat sometimes refers to thermal energy itself. Thermal energy is the kinetic energy of vibrating and colliding atoms in a substance.
