- Initial volume as 2.0 L
- Initial temperature as 60.0°C
- New volume as 30.0 °C
We are required to determine the new volume;
From Charles's law;
Where, are initial and new volume respectively, while are initial and new temperatures respectively;
Rearranging the formula;
Therefore, the new volume that would be occupied by the gas is 1.82 L
