A gas in a cyclinder is held at a constant pressure of 2.30xx10^5 Pa and is cooled and compressed from 1.70m^3 to 1.20m^3 . The internal energy of the gas decreases by 1.40xx10^5J . (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 or not the gas is ideal? Why or why not?
