(a)
Interpretation:
The volume of the balloon that is filled with helium at sea level is to be determined when it floats at higher altitude.
Concept Introduction:
According to Boyle's law, the pressure of sample is inversely proportional to the volume of the sample at constant temperature and at constant mol of gas.
The volume is defined as the quantity of the three dimensional space which is occupied by the

Interpretation:
The volume of the balloon that is filled with helium at sea level is to be determined when it is placed in bath of the liquid nitrogen at
Concept Introduction:
According to Charles law, volume of gas is directly proportional to the temperature at constant pressure and at constant mol of gas.
The volume is defined as the quantity of the three dimensional space which is occupied by the liquid, solid and gas.
