Q. A balloon is filled with $2L$ air in Kota where temperature is $27^{\circ} C$ . What will be the volume of the balloon when it is carried to Shimla where temperature is $0^{\circ} C.?$ (Assume atmospheric pressure is same) :-

Solution:

constant pressure
$\frac{V_{2}}{V_{1}}=\frac{T_{2}}{T_{1}}$
$\frac{V_{2}}{2}=\frac{273}{300}\Rightarrow V_{2}=1.82\,L$
