1. A liquid at temperature 19C is in a beaker. If 3.3 kJ of heat is transferred to the liquid, what is the temperature of the liquid in the unit of C? The mass and specific heat of the liquid are m = 0.72 kg and c = 410 J/(kgC), respectively.

2. How much heat in the unit of kJ is required to completely evaporate 2.21 kg liquid at boiling temperature? The latent heat of the liquid is 1510 kJ/kg?

3. 4.5 kg of a liquid with specific heat c = 3850 J/(kgC) is held in a container. How much heat in the unit of kJ is required to raise the temperature of the liquid by 16C?
