How long does a hot air balloon stay in the air?
It all depends on the amount of fuel you have, most hot air balloons carry 1-2 fuel tanks. On average a hot air balloon burns 25 Gallons of propane an hour, and average fuel tank is a 10 Gallon fuel tank, sometimes 15 Gallons, meaning roughly 45 minutes to an 60 minutes, sometimes its a cool day, you'll require less fuel for more heat, it will last up to an 90 minutes. However, larger balloons carry more fuel, and can stay in the air longer.
Why is it better to launch a hot air balloon on a cold day?
it is better ot launch a hot air balloon on a cold day than on a warm day because the air rises in the atmosphere therefore if you were to go for a cold day you would go very high but if you were to go a ride on a hot day the hot air balloon wont go as high as on the cold day .
