Expert Solution
Step 1
Introduction
Energy cannot be created or destroyed; instead, it can only be converted from one form to another, according to the basic law of thermodynamics. The law of conservation of energy is another name for this rule. Energy can be changed from one form to another, but it cannot be created or destroyed, according to the law. This basically indicates that energy cannot vanish; even if it changes forms, the amount of energy in the universe as a whole does not change.
According to the question,
The heat generated( releasing) is given by =
The work done by the system is given by =
Find- The change in the internal energy
