A gas is held at a constant pressure while its volume decreases from 450 mL to 200 mL. What will the final temperature be if the initial temperature is 25.0 degrees celsius? (Express temperature in K)
According to the ideal gas law: PV=nRT. We can get that under constant pressure, the temperature and volume of the gas has the relationship of V1/T1=V2/T2. And change the 25.0 degrees celsius to 298 K. So the answer is 132.4 K.
