A system undergoes a process during which the heat transfer to the system per degree increase in temperature is given by the equation dQ / dT = 2.0 kJ/°C. The work done by the system per degree increase in temperature is given by the equation dW/dT = 2 - 0.1 T, where T is in °C. If during the process, the temperature of water varies from 100°C to 150°C, what will be the change in internal energy?
a. 125 kJ b. - 250 kJ
c. 625 kJ d. – 1250 kJ
