An ideal gas is trapped inside a cylinder of variable volume. Initially, the gas is at a temperature of 27∘C27^\circ\text{C}27∘C. The piston is compressed such that the volume of the gas is reduced to 60% of its original volume, and its pressure increases by a factor of 2.5.
What is the final temperature of the gas in degrees Celsius?
