Heating causes the air inside the balloon to expand. Some of the warm air leaves through the bottom opening of the balloon, keeping the pressure constant.
The air inside a hot air balloon is the same as normal air around the balloon and the air you're breathing, only heated by the flame inside the balloon, hence HOT AIR balloon.
The density of the air inside a hot air balloon is greatest when the air inside is coolest. As the air inside the balloon is heated, it expands and becomes less dense compared to the surrounding air, causing the balloon to rise.
A hot air balloon is called an hot air balloon because, the inside is heated up to make it less dense, allowing it to rise. Meaning, your heating up the air inside the balloon, hence, the name: Hot air balloon.
The volume of a hot air balloon increases as the air inside the balloon expands when it is heated. As the balloon ascends and the air temperature decreases, the volume of the air inside the balloon decreases as well. The pilot can control the altitude of the balloon by controlling the temperature of the air inside.
The air in a hot air balloon decreases in density when it is heated. As the air inside the balloon is heated, it expands and becomes less dense compared to the surrounding air, creating lift.
In a hot air balloon, the particles refer to the air molecules inside the balloon that are heated by the burner. When the air molecules are heated, they become less dense and rise, creating lift for the balloon. This process allows the hot air balloon to float in the cooler, denser air around it.
Air inside the balloon is heated. Hot air is less dense than the surrounding air, and thus the balloon rises.
The hot air has thermal energy, and when the balloon is up in the air, it also has gravitational potential energy.
A hot air balloon floats because the air inside is heated, making it less dense than the cooler air outside. This creates a buoyant force that lifts the balloon. If the air inside the balloon is not heated, it will not be less dense than the surrounding air, and the balloon will not float.
A hot air balloon rises in the sky because the air inside the balloon is heated, making it less dense than the surrounding air. This causes the balloon to float upwards, as the less dense hot air inside the balloon is lifted by the denser, cooler air outside.
The density of a hot air balloon is the greatest when the air inside the balloon is at its maximum temperature. As the air inside the balloon is heated, it expands and becomes less dense compared to the surrounding air, causing the balloon to rise.
