A 54.2 L sample of gas at 115 K is heated to 345 K,at constant pressure. What volume does the gas now occupy?

Question

Quizplus · Accepted Answer

The volume of a gas at constant pressure is directly proportional to its temperature in Kelvin. This relationship is described by Charles's Law, which can be formulated as V1/T1 = V2/T2. Given the initial volume (V1) of 54.2 L and temperature (T1) of 115 K, and the final temperature (T2) of 345 K, we can find the final volume (V2) by rearranging the formula to V2 = V1 * (T2/T1) = 54.2 L * (345 K / 115 K) = 54.2 L * 3 = 162.6 L, which rounds to 163 L.
