What will be the volume of a gas when 3 litres of it is cooled down from `15^@C` to `-73^@C` at constant pressure.

Explanation

To solve the problem of finding the volume of a gas when it is cooled from 15°C to -73°C at constant pressure, we can use Charles's Law. Charles's Law states that the volume of a gas is directly proportional to its temperature (in Kelvin) when pressure is held constant. The formula for Charles's Law is:

\[ \frac{V_1}{T_1} = \frac{V_2}{T_2} \]
