Thermal Energy Critical Juncture

Front

What happens to the molecules of an object when it gets hotter?

Back

The molecules move faster and have more kinetic energy.

Front

Heat energy transfers from:

Back

hot to cold.

Front

What is a balanced state in which a system is stable, such as when two or more samples are at the same temperature?

Back

Equilibrium.

Front

What happens to the molecules of an object when it gets colder?

Back

The molecules move slower and have less kinetic energy.

Front

What happens to the molecules in the solid ground when lava flows over it and increases the temperature?

Back

The energy of the molecules in the ground increases.

Front

Define thermal energy.

Back

Thermal energy is the total kinetic energy of the molecules in an object.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion.

Front

What is the relationship between temperature and kinetic energy?

Back

As temperature increases, the kinetic energy of the molecules increases.

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).
