Explanation / Answer

heat will be imparted to the water that is heat is coming into the system from outside by burning fuel.

As the system is assumed to be closed thus total volume or mass inside the system remain same thus work is not done in the system

so from 1st la of thermodynamics

Q = U + W

W = 0

so Q = U

so the heat supplied is used to raise the internal enrgy of the water flowing inside which in turn is indicated by the rise in temperature of the outlet water
