Iwill give brainliest ! what is convection? transfer of heat through objects touching source transfer of heat through direct physical contact transfer of heat through electromagnetic waves transfer of heat through the movement of particles

Convection is the movement of denser (cooler) materials falling and less dense (hotter) materials rising. This creates a cycle because the materials usually then heat up or cool, which restarts the movement again. Therefore, convection would be the transfer of heat through the movement of particles.
