Question

the size of weather balloon becomes larger and larger as it ascends up into higher altitude. which gas law explains the above phenomenon

Answer 1

This is because pressure and volume are inversly proportional therefore when the altitude increases the pressure decreases with leads to increase in volume of the air inside the balloon and hence size of the balloon increaes.

Answer 2

Answer: This is explained by Boyle's law.

Explanation:

Boyle's law states that pressure of the gas is inversely proportional to the volume of the gas at constant temperature.

The expression follows:

$P\propto \frac{1}{V}$

Or,

$PV=k$

where, k = constant

At higher altitudes, pressure is low. So, the volume of the gas must be high. Thus, weather balloon becomes larger and larger as it goes above in the sky.

Hence, this is explained by Boyle's law.
