Unit 5 Workman Science Review

Front

What is radiation in terms of thermal energy transfer?

Back

Radiation is a method of thermal energy transfer that moves through empty space.

Front

What type of heat transfer is demonstrated when warm air rises and cool air sinks?

Back

Convection.

Front

Which state of matter is characterized by particles that are far apart and move freely?

Back

Gas.

Front

Which state of matter has a definite shape and volume?

Back

Solid.

Front

What happens to the temperature of a spoon when it is placed in hot mashed potatoes?

Back

Energy in the form of heat is transferred from the warm mashed potatoes to the cooler spoon.

Front

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of thermal energy through the movement of fluids (liquids and gases).

Front

What is the definition of thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance.

Front

What is the difference between heat and temperature?

Back

Heat is the energy transferred between substances due to a temperature difference, while temperature is a measure of the average kinetic energy of particles.

Front

What is an example of radiation?

Back

The warmth felt from sunlight is an example of radiation.
