7th Grade Unit 5 Investigating Thermal Energy

Front

What is a material that allows thermal energy to transfer easily?

Back

A conductor, such as metals like copper, allows thermal energy to transfer easily.

Front

What is a measure of the average kinetic energy of particles in a substance?

Back

Temperature is a measure of the average kinetic energy of particles in a substance.

Front

What is the transfer of thermal energy through currents in liquids and gases called?

Back

Convection is the transfer of thermal energy through currents in liquids and gases.

Front

What is the energy of motion related to the movement of particles in a substance?

Back

Kinetic Energy is the energy of motion related to the movement of particles in a substance.

Front

What is the transfer of thermal energy from a light source to an object or substance?

Back

Radiation is the transfer of thermal energy from a light source (e.g., Sun, fire) to an object or substance.

Front

What is an insulator?

Back

An insulator is a material that does not allow thermal energy to transfer easily.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact do not exchange thermal energy because they are at the same temperature.

Front

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials.

Front

What is the difference between kinetic energy and potential energy?

Back

Kinetic energy is the energy of motion, while potential energy is stored energy based on an object's position.

Front

What is an example of convection in everyday life?

Back

An example of convection is the heating of water in a pot on a stove, where hot water rises and cooler water sinks.
