5a) Transfer of thermal energy creates changes in matter

What are the three main ways heat energy can be transferred?

• Conduction, Convection, and Radiation

• Absorption, Reflection, and Transmission

• Evaporation, Condensation, and Sublimation

• Melting, Freezing, and Boiling

How is heat primarily transferred in solids?

• Through the movement of heated particles

• By the emission of infrared waves

• By vibrating particles transferring energy to neighboring particles

• Through the expansion and rising of less dense regions

Why are solids generally better conductors of heat than liquids or gases?

• Their particles are further apart, allowing for more movement.

• Their particles are held very closely together, leading to more collisions.

• They emit more infrared radiation.

• They have a lower thermal conductivity.

• Yes

• No

What happens to fluid particles when they are heated in a convection process?

• They become denser and sink.

• They stop moving and transfer energy through vibration.

• They gain kinetic energy, spread out, and become less dense.

• They emit infrared waves.

How does the amount of radiation emitted by an object relate to its temperature?

• Hotter objects emit less radiation.

• Colder objects emit more radiation.

• The hotter an object is, the more radiation it emits.

• Temperature does not affect radiation emission.
