When the air is heater, the molecules move faster and expand to fill the volume of the container.
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.
Convection.
When air inside a balloon is heated, the molecules move faster, causing the air to expand and the balloon to inflate. The total mass of the air inside the balloon remains the same, but the density of the air decreases as it becomes less compact.
Convection. In this case, the heated air molecules rise due to their lower density, carrying thermal energy from the heat source at the bottom of the balloon to the cooler top part of the balloon.
When a balloon is heated, the air molecules inside the balloon gain kinetic energy and move faster, causing the air to expand. As a result, the balloon inflates and may eventually burst if it cannot contain the increased pressure from the expanding air molecules.
the heat makes the molecules inside the balloon travel faster, pushing outward on the balloon. This, the balloon expands when heated
When a balloon is heated, the air inside the balloon expands and the molecules move faster, increasing their kinetic energy. This results in a decrease in mass density, as the molecules are more spread out. However, the total mass of the air inside the balloon remains the same.
As the air inside the balloon is heated, its molecules gain kinetic energy and become more active. This causes them to move upwards, carrying the thermal energy towards the top of the balloon. This process creates a temperature difference that causes the balloon to rise.
As the air in the balloon is heated, it expands and becomes less dense, or that is, becomes lighter. This then provides lift to the balloon and the basket. The reason the air in the balloon expands, is because as it is heated, the molecules of air move faster and spread out to fill the entire volume of the balloon.
When the air inside a balloon is heated, its density decreases. This happens because the air molecules gain energy and move farther apart, resulting in a decrease in the air's density.
If the air inside a balloon is heated, the volume will increase because the molecules move faster and spread out, causing the air to expand. Conversely, if the air inside a balloon is cooled, the volume will decrease as the molecules slow down and come closer together.
Two forces that act on a hot air balloon are lift, generated by the heated air inside the balloon being less dense than the surrounding air, and gravity, which pulls the balloon downward.
