Correct the following statement:
The volume of a fixed mass of a gas is directly proportional to its temperature, pressure remaining constant.
It is required to reduce the volume of a gas by 20% by compressing it at a constant pressure. To do so, the gas has to be cooled. If the gas attains a final temperature of 157°C, find the initial temperature of the gas.

At -273°C the volume of a gas is theoretically ______.
According to Charles’s law, at constant pressure, the temperature is inversely proportional to volume.
