dT = Q / cp is the only formula you need


How about this one:
A hot air ballon has a volume of 2500 cubic meters and a takeoff weight (mass) of 250 kg. Outside temperature is 15 degrees C.
At what inside temperature will it take off?

Assume air is an ideal gas with a volume of 22,4 liters per mole and consists of 20% oxygen (O2) and 80% nitrogen (N2).

Don't know the answer off hand, and far too lazy to dig out some books, but a quick look at 'How stuff works...Hot air balloons"...I did discover this line....



"But nothing really got off the ground until the summer of 1783, when the Montgolfier brothers sent a sheep, a duck and a chicken on an eight-minute flight over France."


...I'll be dammned if there ain't a joke in there somewhere...lol.

Maybe,:

 the duck went " quack , quack", the chicken went "cluck, cluck" and the sheep went, "that'll be ten bucks Dale".
