When liquids and gases are heated, they can create convection currents. In liquids, heated areas become less dense and rise, while cooler areas sink, creating a circular flow. In gases, heated air rises and cooler air sinks, generating vertical movements that mix and distribute heat.
When liquids and gases are heated, convection currents are formed. With liquids, the heated fluid rises, cools down and then sinks back, causing a circular motion. In gases, warm air or gas rises and cooler air or gas sinks, creating vertical movements.
Heated air, like what you breath.
They have be heated to liquid form first, and from that they must be heated more to be able to evaporate into the air and become a gas.
expand, causing the air to become less dense and rise.
The two types of air balloons are * One is lifted using heated gases. * Another one is lifted using unheated gases.
its pressure will increase if it is placed in a fixed container, or it will expand if it is free to do so
Hot air balloons are typically filled with hot air, which is lighter than the surrounding cold air, allowing the balloon to float. They do not contain specific gases, other than the air heated to lift the balloon.
