An ideal gas received an amount of heat of 400 J, and its internal energy increased by 156 J. Determine the work of the gas.

| According to the first law of thermodynamics:
∆U = Q – A, where ∆U is the change in the internal energy of the ideal gas when heat is supplied to it (∆U = 156 J), Q is the amount of heat that was transferred to the ideal gas (Q = 400 J), A is the perfect work gas (J).
Let us express and calculate the work of an ideal gas:
A = Q – ∆U = 400 – 156 = 244 J.
Answer: The work done by an ideal gas is 244 J.
