The mass of a hot-air balloon and its cargo (not including the
air inside) is 220 kg. The air outside is at 10.0°C and 101 kPa.
The volume of the balloon is 490 m3. To what temperature
must the air in the balloon be warmed before the balloon will lift
off? (Air density at 10.0°C is 1.244 kg/m3.)

The mass of a hot-air balloon and its cargo (not including the
air inside) is 140 kg. The air outside is at 10.0°C and 101 kPa.
The volume of the balloon is 490 m3. To what temperature must the
air in the balloon be warmed before the balloon will lift off? (Air
density at 10.0°C is 1.244 kg/m3.)

A hot air balloon has a total mass of 750 kg (not including the
air in the balloon) and holds a volume of 2.8 x 10^6 L of air.
Assume the density of the air outside the balloon to be 1.2 kg/m^3
at a temperature of 20 degrees C and the air pressure is 101.3 kPa
inside and outside the balloon. What is the minimum temperature for
the air in the balloon to allow for the balloon to float? You...

A hot air balloon of 25 m in diameter has a mass of 95 kg
including its cage when empty. This balloon is accelerating upward
at an acceleration of 1 m/s^2 in the air at a location where the
atmospheric pressure and temperature are 85 kPa and 13 C
respectively while carrying 3 people with a mass of 70 kg each.

1) Why is a hot air balloon stiff?
2) Is the pressure inside the balloon higher than the pressure
outside (atmospheric pressure)?
3) If the pressure inside is higher than the outside, how is it
explained by ideal gas law?

A hot air balloon has a volume of 65,00 cubic feet of hot air.
The balloon is at sea level on a standard day. If the temperature
of the hot air in the balloon is 1100F, determine the
lifting force of the balloon.

How hot is the air in the top (crown) of a hot air balloon?
Information from Ballooning: The Complete Guide to Riding the
Winds, by Wirth and Young (Random House), claims that the air in
the crown should be an average of 100°C for a balloon to be in a
state of equilibrium. However, the temperature does not need to be
exactly 100°C. What is a reasonable and safe range of temperatures?
This range may vary with the size and...

A hot air balloon has a volume 3,223 m3 . It is
filled with hot air of density 0.96 kg/m 3 . The total mass of
cabin, envelope etc is 350 kg. Find the maximum load of the balloon
in Newtons if the density of surrounding air is
1.29kg/ m3
Use g = 9.8 m/s2 Calculate answer to one decimal.
