The internal energy of the gas increased by 29 J when 44 J of heat was supplied to it. Determine the work done on the gas.

To calculate the value of the work done on the specified gas, we will use the formula: Avn = ΔU – Q.

Variables: ΔU – growth of internal energy (ΔU = 29 J); Q is the supplied heat (Q = 44 J).

Let’s make the calculation: Avn = ΔU – Q = 29 – 44 = -15 J (the work was performed not by external forces, but by the indicated gas).

Answer: The work of external forces on the specified gas is -15 J.
