When heated, the gas received 600 J of heat, while expanding

When heated, the gas received 600 J of heat, while expanding, it performed 200 J of work. Find the value of the change in the internal energy of the gas.

To find the change in the internal energy of the indicated gas, we apply the formula: Q = ΔU + A, whence we express: ΔU = Q – A.

Values of variables: Q – heat received by the specified gas (Q = 600 J); A is the work done by the gas (A = 200 J).

Calculation: ΔU = 600 – 200 = 400 J.

Answer: The internal energy of this gas increased by 400 J.
