According to Charles's Law, the volume of a gas is directly proportional to its absolute temperature (in Kelvin) if the amount of gas and pressure are held constant. Therefore, if the temperature increases, the volume must also increase. The problem does not provide the final temperature, so we cannot determine the new volume exactly. However, we can assume that the temperature increase was not significant enough to cause a large change in volume, so we can estimate the new volume to be slightly larger than the initial volume. Choice E is the closest to this estimate, as it is only slightly larger than 5 L.
