Bill Nye Heat Video Review Flashcard 2024

Front

What is convection?

Back

Convection is the transfer of heat through the movement of liquids or gases. It occurs when warmer areas of a liquid or gas rise and cooler areas sink, creating a circulation pattern.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. It occurs when heat moves from a hotter object to a cooler one through molecular collisions.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves. It does not require a medium to travel through, allowing heat to be transferred through empty space.

Front

How do molecules behave in hot substances?

Back

In hot substances, molecules move more rapidly due to increased energy.

Front

How do molecules behave in cold substances?

Back

In cold substances, molecules move more slowly compared to those in hot substances.

Front

What is an example of conduction?

Back

An example of conduction is a pancake getting heat directly from a hot grill.

Front

What is an example of convection?

Back

An example of convection is the spiral paper on top of a pencil spinning due to the movement of warm air.

Front

What happens to the movement of molecules as temperature increases?

Back

As temperature increases, the movement of molecules becomes more vigorous.

Front

What is the relationship between temperature and molecular movement?

Back

The hotter something is, the more its molecules move.

Front

What is the primary method of heat transfer in liquids?

Back

The primary method of heat transfer in liquids is convection.
