The volume of the gas at  is
 is  .
.
Further Explanation:
Consider the pressure of the gas to be constant.  
The change in the volume of the gas when the temperature of the gas is varied by keeping the pressure of the gas at a constant value is defined by the Charles' Law.
Concept:
According to the Charles law, the volume of the gas is directly proportional to the temperature of the gas at constant pressure.
The Charles' law can be stated as:

The above expression can we written as.

Convert the temperature of the gas into kelvin.

Here, T is the temperature in kelvin and  is the temperature in centigrade.
 is the temperature in centigrade.  
The initial temperature of the gas is  . The temperature of the gas in kelvin is.
. The temperature of the gas in kelvin is.  

The final temperature of the gas is  . The temperature in kelvin is.
 . The temperature in kelvin is.  

Substitute the values of temperature and volume in the expression of the Charles' Law.  

Thus, the volume of the gas at  will be
 will be  .
