A gas-filled balloon having a volume of 3.60 L at 1.15 atm and 20°C is allowed to rise to the stratosphere (about 30 km above the surface of the Earth), where the temperature and pressure are −50°C and 5.40 × 10−3 atm, respectively. Calculate the final volume of the balloon.

The new volume of the balloon will be 583.5 L

Explanation:

To calculate the volume when temperature and pressure has changed, we use the equation given by combined gas law.

The equation follows:

where,

are the initial pressure, volume and temperature of the gas

are the final pressure, volume and temperature of the gas

We are given:

Putting values in above equation, we get:

Hence, the new volume of the balloon will be 583.5 L

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.
