A hot air balloon is hovering at an altitude of 6000 meters. The pilot decides that it is time to descend and turns off the balloon's burners. Once the balloon reaches the ground, the gas inside the balloon occupies 980 m^3 and is at atmospheric pressure. If the pressure of the gas inside of the balloon was 75,000 Pascals at its highest altitude, what was the volume of the gas at that time?

Assuming temp is constant?

75kPa*V=101kPa*980

solve for V

Where did you get the 101kpa.

I am getting v2=p1v1/p2

(6000)(980m^3) divided by 75000 = 78.4 m^3
