I had meet a problem when I study the concept of the hot air balloon. The equation was giving
Load = P*V*(1/TempAir - 1/TempBalloon)/R
Then I reverse to
TempBalloon = 1/[1/TempAir -Load*R/(P*V)]
When the volume is less then 1m^3, the temperature calculated giving negative temperature (In kelvin and degree also) but suppose had a greater in temperature with my understanding for the theory.
So is that any wrong in the equation or my understanding?
