Given:
Increase in Internal Energy, U = 114   J
Energy transferred from system, Q = 21   J
Work done is calculated using the first law of thermodynamics.
First Law of thermodynamics:
Q = U + W
CALCULATION:
Plugging value of heat and internal energy in first law of thermodynamics we get,
21   J = 114   J + W W = 114 21   J = 135   J
Work done is 135 J.
