# certain flexible weather balloon contains helium gas at a volume of 855 L . Initially, the balloon is at sea level where the temperature is 25 °C and the barometric pressure is 73 0 torr. The balloon men rises to an altitude of 6000 ft, where the pressure is 6 0 5 torr and the temperature is 15  ° C . What is the change in volume of the balloon as it ascends from sea level to 6 000  ft ?

Interpretation Introduction

Interpretation:

To calculate the change in the volume of balloon as it ascends from sea level to 6000 ft.

Concept Introduction:

The combine gas equation is used to calculate the change in pressure, volume or temperature at two different conditions.

P1V1T1=P2V2T2.

Explanation

Given information:

P1 = 730 torr

V1 = 855 L

T1 = 25 Â°C = 273+25 = 298 K

P2 = 605 torr

T2 = 15Â°C = 273+15 = 288 K

By using combine ideal gas equation we can calculate the new volume with the help of other given information.

Plug the values in given combine gas equation:

P1V1T1=P2V2T2
