Given data
Initial temperature of air Ti=300 K
Vf (final volume of air)=2Vi (initial volume of air )
To find
Final temperature
Solution
Since no energy is lost by thermal conduction during the process we categorize this process as an adiabatic one.Hence we apply;
Where air is predominantly a diatomic gas Y=1.4m
Substitute the given values
So
