Final answer:
Under Charles's Law, if the temperature of a gas goes down, the volume will also go down, leading to a smaller V2.
Step-by-step explanation:
According to Charles's Law, the volume (V2) of a gas is directly proportional to its temperature on the Kelvin scale when the pressure and the amount of gas are held constant. Therefore, if the temperature of a gas is decreased, Charles's Law indicates that the volume of the gas will decrease as well. This relationship is often represented visually in a graph where volume increases with increasing temperature; the inverse is also true, so a decreasing temperature leads to a smaller volume.
