What else can I help you with?
What is the name of the process by which air moves and carries heat energy with it?
In thermodynamics it is called Enthalpy for all possible means: radiation, convection, diffusion. It always has a negative value.
Body heat tranferred to the air by what?
Body heat is transferred to the air primarily through convection and radiation. Convection occurs as the warm air around the body rises and cooler air moves in to take its place, carrying away heat. Radiation involves the transfer of heat through electromagnetic waves from the body to the surrounding air.
What does air do when it is heated in convection?
When air is heated in convection, it becomes less dense and rises. As it rises, it displaces cooler air, which then becomes heated and rises as well. This creates a continuous cycle of warm air rising and cool air sinking, which is known as convection.
How does convection and radiation heat a room?
Because the air closer to the heater heats up first. It then gets warmer and less dense and rises to the top of the room, which pushes down the cooler air that is already up at the top. Then that air warms up and rises to the top, pushing the cooler air down. This creates the Convection Current and that is how the room gets heated : )
What step is not part of the convection cycle?
Cooked air rises creating a high pressure system below
A mass of warm air rises when it collides with a mass of cold air What is this process called?
This process is called convection. The warmer air rises because it is less dense than the colder air, creating a convection current.

What is rising warm air called?
Rising warm air is called convection. As warm air rises, it creates convection currents that circulate heat and moisture in the atmosphere.

What is a cycle in which air is warmed and warm air rises and air is cooled and cooled air sinks?
The process you are describing is known as convection. This cycle occurs when a fluid, in this case, air, is heated, causing it to expand and rise due to lower density. As the air rises, it cools, becomes denser, and eventually sinks back down to be reheated, thus continuing the convection cycle.
Warm air rises and cool air sinks?
Convection
What method does campfires transfer heat?
Campfires transfer heat primarily through convection and radiation. Convection occurs as the hot air rises from the fire, creating air currents that spread the heat. Radiation involves the emission of electromagnetic waves, which heat objects or surfaces that are in the fire's line of sight.
Is the inside of how a greenhouse works conduction convection or radiation?
The inside of a greenhouse primarily works through convection. Solar energy penetrates the glass walls, heating the air inside. The warm air rises, creating a convection current that circulates heat throughout the space.
When warm air rises and cool air sinks in what is it called?
This phenomenon is called convection. As warm air rises, it cools down and becomes denser, causing it to sink back down. This continuous cycle is responsible for many weather patterns and is essential for distributing heat around the Earth.
