CoachHeat transfer by convection requires a fluid (liquid or gas) to transfer heat. The fluid circulates due to temperature differences, carrying heat from one place to another. Convection is more efficient in fluids compared to solids because molecules in fluids can easily move and transfer heat through their motion.

Can heat transfer by convection happen in a solid?
No, heat transfer by convection requires the movement of fluids to transfer heat. Since solids do not have the ability to flow like fluids, heat transfer by convection does not typically occur in solids. Heat transfer in solids usually occurs through conduction, where heat is transferred through the vibration of particles.
Does heat travel through space by convection?
No, heat does not travel through space by convection as convection requires a medium like air or water to transfer heat. In the vacuum of space, heat is mainly transferred through radiation.
What type of heat transfer requires air movement?
Convection heat transfer requires air movement. This occurs when heated air rises, creating a flow that transfers heat from one location to another.
Does convection require medium?
yes
How does Transfer of heat energy in a liquid?
Heat transfer in liquids can occur through conduction, convection, and radiation. Conduction is the transfer of heat through direct contact between molecules within the liquid. Convection involves the movement of the liquid itself, carrying heat energy through the fluid. Radiation is the transfer of heat through electromagnetic waves.
