A closed system of constant volume.. 30 kJ solved problem



A closed system of constant volume experiences a temperature rise of 25°C when a certain process occurs. The heat transferred in the process is 30 kJ. The specific heat at constant volume for the pure substance comprising the system is 1.2 kJ/kg°C, and the system contains 2.5 kg of this substance. Determine : (i) The change in internal energy ; (ii) The work done.
