Unit 2 Heat & Energy Transfers

Front

What is replication in scientific experiments?

Back

Replication is when a scientist repeats an experiment exactly to see if they get the same results.

Front

What is the direction of heat transfer?

Back

Heat transfer always goes from hot to cold.

Front

How does energy move when an ice cube is placed in a hot pan?

Back

The heat will travel from the pan to the ice cube.

Front

What method of energy transfer occurs when standing in front of a campfire?

Back

The method of energy transfer is radiation.

Front

What type of energy is associated with temperature?

Back

Thermal energy is associated with temperature.

Front

What is conduction?

Back

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

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases).

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves, such as heat from the sun.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact do not exchange heat, meaning they are at the same temperature.

Front

What is the difference between thermal energy and temperature?

Back

Thermal energy is the total energy of all particles in an object, while temperature is a measure of the average kinetic energy of those particles.
