7th Grade Fall Semester Exam Review

Front

What is heat transfer?

Back

Heat transfer is the movement of thermal energy from one object or substance to another due to a temperature difference.

Front

What are the three types of heat transfer?

Back

The three types of heat transfer are conduction, convection, and radiation.

Front

Define conduction.

Back

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

Front

Define convection.

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature and density.

Front

Define radiation.

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as infrared radiation.

Front

What is Newton's First Law of Motion?

Back

Newton's First Law states that an object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by a net external force.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

Give an example of conduction in everyday life.

Back

An example of conduction is when a metal spoon gets hot after being placed in a hot pot of soup.

Front

Give an example of convection in everyday life.

Back

An example of convection is the way warm air rises and cool air sinks in a room, creating a circulation of air.

Front

Give an example of radiation in everyday life.

Back

An example of radiation is feeling the warmth of the sun on your skin.
