When we relax in a hot tub, our body heats up. What form of heat transfer takes place?

Convection

500
the reason cool material sinks and warm rises in a convection current

Explain the difference between conduction, convection, and radiation.

  • Conduction is the transfer of heat through direct contact between particles.
  • Convection is the transfer of heat through the movement of fluids (liquids or gases).
  • Radiation is the transfer of heat through electromagnetic waves.
