Two heavy men can be carried by a balloon with hot air through the principle of buoyancy. When the balloon is filled with hot air, it becomes lighter than the surrounding air because hot air is less dense than cold air. This creates a pressure difference, causing the balloon to rise.
The amount of hot air in the balloon needs to be carefully controlled to ensure that it can lift the weight of the two men. The balloon must be large enough to displace a volume of air equal to the combined weight of the men, while the hot air inside the balloon must be heated to a temperature that provides enough lift.
By carefully managing the temperature of the hot air and the size of the balloon, it is possible for two heavy men to be carried by just a balloon with hot air. This is a common practice in hot air ballooning, where passengers are lifted into the sky using the same principles of buoyancy.

A balloon with hot air can carry two heavy men because of the principles of buoyancy and thermal expansion.
Buoyancy
Buoyancy is an upward force exerted by a fluid that opposes the weight of a partially or fully immersed object. In the case of a balloon, the fluid is air. The amount of buoyancy force depends on the density difference between the object and the fluid.
Thermal Expansion
Thermal expansion is the increase in the volume of an object when its temperature increases. When air is heated, it expands and becomes less dense.
How a Balloon with Hot Air Carries Heavy Men
When hot air is pumped into a balloon, it expands and becomes less dense than the surrounding cooler air. This creates a buoyancy force that pushes the balloon upwards.
The greater the temperature difference between the air inside and outside the balloon, the greater the buoyancy force. As the balloon ascends, the air outside becomes colder and denser, increasing the buoyancy force even further.
If the buoyancy force is greater than the combined weight of the balloon and the two heavy men, the balloon will continue to ascend.
Additional Factors
In practice, several other factors contribute to the ability of a balloon with hot air to carry heavy men:
- Balloon Size: Larger balloons have a greater surface area, allowing them to displace more air and generate more buoyancy force.
- Balloon Shape: Spherical or oval balloons have a more efficient shape for generating buoyancy than irregularly shaped balloons.
- Air Temperature: Higher air temperatures increase the buoyancy force.
- Payload Weight: The total weight of the men and any other payload will affect the balloon's ability to ascend.
By carefully controlling these factors, it is possible for a balloon with hot air to carry significant weight, including two heavy men.
