The natural gas in a storage reservoir, under a pressure of 1.00 atmosphere, has a volume of 2.74 × 109 l at 20.0°c. the temperature at a later date falls to –20.0°c, but the pressure remains constant. calculate the volume that the gas now occupies

Answer : The final volume of gas will be,

Explanation :

Charles' Law : It is defined as the volume of gas is directly proportional to the temperature of the gas at constant pressure and number of moles.

or,

where,

= initial volume of gas =

= final volume of gas = ?

= initial temperature of gas =

= final temperature of gas =

Now put all the given values in the above formula, we get the final volume of the gas.

Therefore, the final volume of gas will be,
