Convection
Thermal transfer by convection takes place in materials that are fluids or gases. In this process, heat is transferred through the movement of the material itself, creating a circulation pattern that transfers heat energy. Convection is a key mechanism for heat transfer in liquids and gases.
Mode of energy transfer in fluids is convection.
Heat
Convection is the type of thermal energy transfer that occurs when fluids move. This process involves the transfer of heat through the movement of a fluid, such as air or water, causing molecules to carry thermal energy from one place to another.
The movement of thermal energy from one place to another is called heat transfer. It can occur through conduction, 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.
Radiation is the type of thermal energy transfer that does not require particles to take place. Radiation can occur through empty space and does not rely on the movement of particles like conduction and convection do.
Conduction is the transfer of thermal energy through direct contact of molecules. Convection is the transfer of thermal energy through the movement of fluids like liquids or gases. Radiation is the transfer of thermal energy through electromagnetic waves. Together, they enable heat to be transferred from one object to another.
In fluids such as liquids and gases, heat can travel through convection. This occurs when particles in the fluid transfer thermal energy as they move from one place to another. Convection is an efficient method of heat transfer in fluids.
The movement of matter during convection is what transfers thermal energy.The air or liquid currents help transferring thermal energy through convection as the currents of higher temperature are of less density (lighter) and move upwards while that of less temperature are of higher density (heavier) and move downwards.Convective heat transfer, often referred to simply as convection, is the transfer of heat from one place to another by the movement of fluids (liquids or gases). Convection is usually the dominant form of heat transfer in liquids and gases.
water/gasses
Materials that allow convection to take place are usually fluids or gases, as they can easily move and transfer heat through the process of convection. Solids can also participate in convection to a lesser extent, especially if they have some degree of flexibility or ability to transmit heat through them. In general, materials that can move or flow are more likely to enable convection.
