According to Charles's Law, at a constant pressure, the volume of a gas is directly proportional to its temperature in kelvins. Therefore, we can use the equation V1/T1 = V2/T2 to find the new volume (V2). Plugging in the initial volume (V1 = 4.00 L), the initial temperature (T1 = 400. K), and the final temperature (T2 = 300. K), we get:
4.00 L / 400. K = V2 / 300. K
Solving for V2, we get:
V2 = (4.00 L / 400. K) x 300. K = 3.00 L
Therefore, the new volume of the gas sample is 3.00 L. Answer: C) 3.00 L.
