(a)
Interpretation:
Concept Introduction:
The change in internal energy is equal to sum of heat and work done.
The mathematical expression is given as:
Where, q = heat and w = work done.
If heat is released from the system, q is negative and if heat is absorbed by the system, q is positive.
If work is done on the system, w is positive and if work is done by the system, w is negative.
