Physics answer for 10 points.?

A gas in a cylinder is held at a constant pressure of 2.2×10^5 Pa and is cooled and compressed from a volume of 1.79 m^3 to 1.30 m^3. The internal energy of the gas decreases by 1.37×10^5 J.
Find the work done by the gas.

Find the absolute value |Q| of the heat flow into or out of the gas.

dQ=dW+dU

dW=pdV;p=2.2Ã10^5;dV=91.79-1.3)

dU=1.37Ã10^5
