Answer 1

Charle's Law states that - At constant pressure, for a fixed amount of gas, volume of the gas varies directly with absolute temperature (kelvin temperature).
V∝T (at constant pressure)

Charles's Law examines the effect of changing temperature on volume. To isolate these variables, pressure must remain constant. If the container volume is adjustable, the volume will increase, and the pressure will remain the same.
