Thermal Energy Transfer Concepts

What is the direction of thermal energy flow?

• Thermal energy does not flow

• From a region of lower temperature to higher temperature

• From a region of higher temperature to lower temperature

• From a region of equal temperature to another region of equal temperature

Which mechanism of thermal energy transfer does not require particles?

• Convection

• Radiation

• Conduction

• Evaporation

How does thermal conduction transfer energy?

• By the flow of fluids

• Through the movement of electromagnetic waves

• By the bulk movement of matter

• Through vibrations of adjacent particles in solids

Which type of surface is best at absorbing and emitting infrared radiation?

• Smooth and matte surfaces

• Rough and shiny surfaces

• Rough and matte surfaces

• Smooth and shiny surfaces

Why do objects with higher temperatures emit more infrared radiation?

• Because they have more particles

• Because they emit less energy per second

• Because they emit more energy per second

• Because they absorb more infrared radiation
