A sample of gas has a volume of 3.40 L at 10.0^°C.What will be its volume at 100.0^°C, pressure remaining constant?

Question

According to Charles' Law, at constant pressure, the volume of a given amount of gas is directly proportional to its absolute temperature. Therefore, we can use the equation V1/T1 = V2/T2, where V1 is the initial volume (3.40 L), T1 is the initial temperature in Kelvin (10.0°C + 273 = 283 K), V2 is the final volume (unknown), and T2 is the final temperature in Kelvin (100.0°C + 273 = 373 K). Solving for V2, we get V2 = (V1 x T2)/T1 = (3.40 L x 373 K)/283 K = 4.48 L. Therefore, the answer is B.
