In a rigid tank, water is heated by a Benson burner while being stirred by a paddle wheel. Initially, the internal energy of the water is 800 kJ. During a heating process of the Benson burner, the paddle wheel delivers 100 kJ of work (mechanical energy) during the stirring while 200 kJ of thermal energy (heat) is dissipated from water to the surrounding. At the final state, the internal energy of water is 1400 kJ. Find:
a) Is the volume of this rigid tank going to change during the heating process?
b) Is this system a closed system or control volume system and explain why
c) List the forms of energy transfer involved in this system
d) The heat transferred from the Benson burner to water during this process?
