What else can I help you with?
The transfer of heat by the movement of molecules which carry the heat is called?
CONVECTION
What term is used to describe hot air rising to carry heat?
The term is "convection." Convection is the process where hot air rises due to its lower density compared to cold air, allowing it to carry heat upward.
What kinds of matter carry heat by convection?
Fluids such as air and water are common substances that carry heat through convection. As these fluids are heated, they become less dense and rise, carrying heat with them. This creates a flow of warmer fluid that transfers heat to cooler areas by convection.
Does convection transfer heat by electromagnetic waves?
No, convection transfers heat through the movement of fluids, such as air or water, which carry thermal energy from one place to another. Electromagnetic waves transfer heat through radiation, not convection.
Why does convection not happen in a vacuum?
Convection requires a medium, such as a gas or liquid, to transfer heat through the motion of the medium itself. In a vacuum, there is no medium to carry the heat, so convection cannot occur. Heat transfer in a vacuum primarily occurs through radiation.

What 2 processes transport Earths energy surpluses poleward from the tropics?
Wind and water. Air currents (wind) carry heat poleward. This is mainly heat transfer by convection. Water currents carry heat poleward. This is heat transfer by convection and conduction.
What is the movement of heat without matter to carry it is?
You think probable to convection or radiation.

No, convection transfers heat through the movement of fluids, such as air or water, which carry thermal energy from one place to another. Electromagnetic waves transfer heat through radiation, not convection.

explain how heat transfer can be minimised by convection in a vacuum flask?
Heat transfer by convection can be minimized in a vacuum flask because there is no air (or fluid) inside to carry heat through convection currents. The vacuum creates a barrier that reduces heat transfer by convection, as there is no medium for the heat to move through. This helps to keep the contents of the vacuum flask at their original temperature for a longer period of time.
What direction does convection heat transfer move?
Convection heat transfer moves from regions of higher temperature to regions of lower temperature. This occurs through the motion of fluids, such as air or water, which carry heat energy with them as they circulate.
Why doesn't convection happen in solid?
Convection requires the movement of a fluid, such as liquid or gas, to transfer heat. In a solid, the particles are tightly packed and cannot easily flow or move past each other to carry heat through convection. As a result, convection does not occur in solids.
When heat travels through air is that radiation?
Heat transfer through air can occur through conduction, convection, and radiation. In the case of radiation, heat is transferred through electromagnetic waves without the need for a medium to carry the heat.
