Study Notes

Heat Energy

  • Heat energy izes from the movement of particles within a substance.
  • Faster particle movement equates to more heat energy.

Conduction

  • Heat moves through direct contact between materials.
  • Example: A metal spoon heating up in hot soup.

Convection

  • Heat moves through the movement of fluids or gases.
  • Example: Warm air rising and cool air sinking in a room.

Radiation

  • Heat moves through electromagnetic waves, not needing a medium.
  • Example: Heat from the Sun reaching Earth.

Light Energy

  • Light is a form of electromagnetic radiation visible to the human eye.
  • Light has particles called photons that travel in waves.

Transmission

  • Transmission describes how much light and sound waves can pass through something.

Reflection

  • Reflection is when waves (light or sound) bounce off surfaces.

Refraction

  • Refraction is when waves (light or sound) change direction when passing between different mediums, changing speed.

Absorption

  • Absorption is when energy from light or sound is taken in by a substance, often becoming heat.

Diffusion

  • Diffusion is the scattering or spreading of energy (light or sound) as it moves through a medium or after interacting with a surface.
