A sample of an ideal gas is enclosed in a cylinder. The initial temperature of the gas is 177 ∘C177\ ^\circ\text{C}177 ∘C and the initial product of its pressure and volume is 7200 J.
The gas is compressed at a constant pressure, with 2400 J of work done on the gas.
What is the final temperature of the gas?
