A balloon is inflated with air in a warm living room `(24^(@)C)` to a volume `2.5 L`. It is taken out on a very cold winter's day `(-30^(@)C)` . Assuming that mass of air and pressure inside the balloon.

A balloon is filled with cold air and placed in a warm room. It is NOT in thermal equilibrium with the air of the room until

A weather balloon filled with hydrogen at 1 atm and 27^(@)C has volume equal to 1200 litres. On ascending, it reaches a place where temperture is -23^(@)C and pressure is 0.5 atm. The volume of the balloon is
