In a solar energy storage system, a fluid of variable specific heat is used to store the energy. The variable specific heat is given by the relation Cp = 0.04 T + 0.7 kJ/kg K, where T is in °C. If the temperature rise of the fluid is from 20°C to 40°C, the amount of energy stored per unit mass will be
1
38 kJ
2
14 kJ
3
24 kJ
4
76 kJ
