Why do hot air balloons work?
Hot Air Balloons work because of the hot air.The hot air rising stays in the balloon and carries it upward.
How does a hot air balloon stay up?
it stays up because there is a fire inside of it and the gases from the fire focuses the hot air ballon to stay up
What level of the atmosphere can a hot air balloon travel?
It varies. Normally, a hot air balloon can go as high as it wants as long as the air inside is still less dense than air surrounding it.
When a room is hot is it better to have the ceiling fan turn clockwise or counter clockwise?
When a room is hot it is better to have the ceiling fan turned counter clockwise. This forces the air to blow down. In the winter the fan should turn clockwise to keep the warm air higher.
How do you keep an hot air balloon in the air indefinitely?
To keep a Hot air balloon in the sky indefinitely you must keep all the air sealed and warm. The Hot air's lower density will keep it above the more dense, colder air. To demonstrate this put air inside a bottle and place it on-top of water. Notice how it stays "afloat". ======================================================== To keep a hot air balloon aloft indefinitely, the temperature of the air inside the balloon must be hot enough so that the difference in weight of the air inside the balance and an equivaletnt volume outside of the balloon equals or exceeds the total weight of the balloon and passengers. It doesn have to be air tight. Hot air balloons are open on the bottom. But it has to be air tight enough that the burner will be capable of keeping the air hot enough to maintain altitude.
Why do hot air balloons work?
Hot Air Balloons work because of the hot air.The hot air rising stays in the balloon and carries it upward.
How does a hot air balloon stays in the air?
A hot air balloon can stay in the air because the hot air is less dense than cool air. The hot air that is blown into the balloon causes it to rise and a burner is used to heat the air inside of the balloon to keep it floating.
How does a hot water radiator heat a room?
The hot water heats the metal of the radiator, which heats the surrounding air. The warm air circles round the room.
How does a hot air balloon stay up?
it stays up because there is a fire inside of it and the gases from the fire focuses the hot air ballon to stay up
How does a room with a hot radiator get hot?
The room heats by convection transfer into the air, aided by humidity produced when water is heated.
Why are Ventilators are kept at the top of a room?
Hot air always moves up.ventilators are kept in house because it helps hot air to move through.
What exactly is air conditioning?
Air conditioning is removing hot air with cold air. For example we use air conditioner that removes hot air by blowing cold air from a refrigeration cycle into a room.
Why are room heaters placed at a lower level?
Room heater are placed on a lower level because the air coming from the room heater is hot and hot air is light so it will go up and resulting in keeping us warm.
What is hot air is lighter than cool air?
a.the molecule is farther apart. b.the molecules are closer. c.the hot air takes up less room d.the hot air is light
How does hot air balloon stays up?
The air inside the balloon is heated with a propane burner. As air is warmed, it becomes less dense (lighter) and rises.
What type of gas is used in a hot air balloon?
A hot air balloon is normally powered with propane. Other than that, it is just ordinary air used inside the balloon.
How does thermal energy from a radiator reach the other side of the room?
Hot air from a radiator reaches the other side of a room by convection current. Convection current is when hot water/ air rises, hot water/ air cools, cool water/ air sinks, cool water/ air warms and then the cycle starts over.
