Question

During a compression at a constant pressure of $250 P a$ , the volume of an ideal gas decreases from $0.80 m^{3}$ to $0.20 m^{3}$ . The initial temperature is $360 K$ , and the gas loses $210 J$ as heat. What are the final temperature of the gas?

Solution

From the ideal gas equation $P_{i} V_{i} = P_{f} V_{f}$
Since the pressure (and also the number of moles) don't change in this process, then the volume is simply proportional to be (absolute) temperature. Thus, the final temperature is $1 / 4$ of the initial temperature. The answer is $90 K$ .
