Given a fixed amount of gas held at constant pressure, calculate the volume it would occupy if a 3.50 L sample were cooled from 90.0^oC to 30.0^oC.

According to Charles's Law, at constant pressure, the volume of a gas is directly proportional to its absolute temperature. Therefore, V1/T1 = V2/T2, where V1 is the initial volume, T1 is the initial temperature, V2 is the final volume (what we want to find), and T2 is the final temperature. We can rearrange this equation to solve for V2: V2 = V1(T2/T1). Plugging in the values, we get V2 = 3.50 L * (303 K/363 K) = 2.92 L. Therefore, the answer is D.
