- Conduction : Transfer of thermal energy through direct contact of particles.
- Convection : Transfer of thermal energy by movement of fluids.
- Radiation : Transfer of energy through electromagnetic waves without particles.
- Thermal Energy Transfer : Movement of heat from warmer to cooler objects.
- Heat : Energy transferred due to temperature difference.
- Temperature : Measure of average kinetic energy of particles.
- Thermal Energy : Total energy of all particles in a substance.
- Conductor : Material that allows heat to pass through easily.
- Insulator : Material that slows down heat transfer.
- Convection Current : Circular movement of fluid caused by heating.
- Less Dense : Particles spread out and rise.
- More Dense : Particles are closer together and sink.
- Fluid : A substance that can flow such as a liquid or gas.
- Ultraviolet : High-energy invisible radiation from the sun.
- Infrared : Invisible radiation associated with heat.
