A cylinder оf ideаl gаs with crоss sectiоnаl area of 300 cm^2 has one fixed end and a piston on the other end that is free to move. Suppose that a constant external force is exerted on the piston, pushing it into the gas with a constant force of 1000 N. The piston is pushed outward from the cylinder of gas by 10 cm. If this is done by heating 3 moles of gas, how much did the temperature of the gas change? Recall, the ideal gas law PV=nRT, and R = 8.314 J/mole.
