When hot and cold air meet the hot air rises to the top. Which process causes the hot air to rise?
Convection
What property causes a hot air balloon to rise?
heat
Which process causes the hot air to rise?
The process that causes hot air to rise is called convection. As air is heated, it becomes less dense and more buoyant, causing it to rise. This creates vertical air currents that continuously cycle warm air upwards.
Who was driving the Hindenburg?
Because it gets filled with hydrogen and it causes it to rise since it gets how. As we know hot air rises. Because it gets filled with hydrogen and it causes it to rise since it gets how. As we know hot air rises.
What force brings a hot air balloon to earth after the hot air is let out?
Erm.. no.. i believe its Buoyancy... this force causes u the hot air balloon to rise.. not Gravity..
Why are hot air balloons able to rise into the air?
Hot air balloons rise because when the air inside the balloon is heated, it becomes less dense than the surrounding cooler air. This difference in density creates lift, causing the hot air balloon to float upward.
What source is used to fly hot air balloons?
Wind !... The balloons are filled with hot air, which causes them to rise. They are then at the mercy f the wind direction.
When hot and cold air meet the hot air rises to the top Which process causes the hot air to rise?
The hot air rises due to convection, which is the transfer of heat through the movement of liquids or gases. When hot and cold air meet, the hot air expands and becomes less dense, causing it to rise above the denser, cooler air.
What heat sources make things rise?
Fire makes things rise as it is a very strong source of heat. So does hot air. Fire causes hot air and because hot air is lighter than cold air, it rises. Is that good? (my first answer X3)
Why does a balloon need hot air?
A balloon needs hot air to make it rise because hot air is less dense than cold air. When the air inside the balloon is heated, it becomes lighter and causes the balloon to lift off the ground and float in the air.
Why does hot air rise while cold air sinks?
Hot air rises because it is less dense than cold air. When air is heated, its molecules move faster and spread out, making the air less dense. This lower density causes the hot air to rise, while the denser cold air sinks.
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.
