Warm air often goes to the upper parts of the house.

Question

Warm air often goes to the upper parts of the house.

Whar is the name of the process by which air moves and carries heat energy with it ?

Since this is not my area of expertise, I searched Google under the key words "heat convection" to get these possible sources:

I hope this helps. Thanks for asking.

Convection

Answer 1

The process by which air moves and carries heat energy with it is called convection. Convection occurs when warmer air rises and cooler air sinks, creating a circulation of air. This movement of air helps distribute heat throughout the space. Warm air tends to rise and accumulate in the upper parts of the house, while cooler air settles towards the lower parts. This is why you may experience warmer temperatures in the upper levels of a house. Convection is an important mechanism for heat transfer and is involved in many natural processes, such as weather patterns and the heating of fluids.
