Thermal Energy Transfer Flashcard

Front

What happens to the speed of particles in a gas when the temperature increases?

Back

The speed increases.

Front

What is the method of thermal energy transfer that involves the movement of fluids due to differences in temperature and density?

Back

Convection.

Front

Describe the process of convection in a pot of boiling water.

Back

Heat causes water to circulate as warmer water rises and cooler water sinks.

Front

What is the process called when thermal energy is transferred through direct contact between materials?

Back

Conduction.

Front

What happens to the temperature of two substances in contact over time?

Back

The temperatures will equalize.

Front

Define thermal energy.

Back

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

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 or gases).

Front

What is radiation?

Back

Radiation is the transfer of thermal energy through electromagnetic waves.

Front

Give an example of conduction in everyday life.

Back

Touching a hot stove and feeling the heat transfer to your hand.
