A gas in a cylinder is held at a constant pressure of 2.30 X 105 Pa and is cooled and compressed from 1.70 m3 to 1.20 m3• The internal energy of the gas decreases by 1.40 X 105 J.
(a) Find the work done by the gas.
(b) Find the absolute value |Q| of the heat flow into or out of the gas, and state the direction of the heat flow.
(c) Does it matter whether the gas is ideal? Why or why not?
