Unit 3 Lesson 2: Energy Transfer Lesson Review

Front

What is the process called when the sun transfers energy to Earth?

Back

Radiation

Front

Conduction involves the transfer of energy from the ______-moving particles of the warmer object to the slower-moving particles of the cooler object.

Back

faster

Front

What evidence supports that heat and light energy are being used in this picture?

Back

the food feels warm

Front

Fill in the blank: A substance with a lower specific heat will _______ compared to a substance with a higher specific heat.

Back

warm up more quickly

Front

Fill in the blank: Convection is the transfer of heat through ______.

Back

motion

Front

Define conduction in terms of energy transfer.

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is convection and how does it occur?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) due to differences in temperature.

Front

Explain the concept of specific heat.

Back

Specific heat is the amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius.

Front

What is the difference between conduction and convection?

Back

Conduction is heat transfer through direct contact, while convection is heat transfer through the movement of fluids.

Front

Give an example of radiation in everyday life.

Back

The warmth felt from sunlight is an example of radiation.
