Hi

I'm stuck on a problem:
Total mass of airballon and two people=660 kg
Volume of airballon=7500 m^3
Outside temperature=20°C
Density of air: 2.1968-0.2796*ln(T). T is in °C.

What is the temperature of the air in the airballon?

Thanks!

When?

I suppose you mean when the temperature is sufficient to rise the balloon, the basket and the people..

Try with this formula, knowing that the balloon rises when the lift is superior to the total weight:

Btw, check out the internet for a °K to °C converter.
