Heat, Temperature & Thermal Energy

Front

Energy due to motion is ____________ energy.

Back

Kinetic energy is the energy that an object possesses due to its motion.

Front

The transformation of energy when a kid eats spaghetti and then plays with toys is __________.

Back

Chemical to mechanical energy transformation occurs when the body converts the chemical energy from food into mechanical energy for movement.

Front

How does thermal energy flow in a glass of iced tea?

Back

Thermal energy flows from the tea (hot) to the ice (cold) until thermal equilibrium is reached.

Front

Thermal energy ALWAYS moves from _____ to _____.

Back

Thermal energy always moves from hot to cold.

Front

Heat will continue to flow until a system has reached __________.

Back

Thermal equilibrium is the state where two objects in contact no longer transfer heat between them.

Front

What is the definition of thermal energy?

Back

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

Front

What is temperature a measure of?

Back

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

Front

What is the difference between heat and temperature?

Back

Heat is the transfer of thermal energy, while temperature is a measure of the average kinetic energy of particles.

Front

What happens to the thermal energy of ice when it melts?

Back

The thermal energy of ice increases, causing the ice to change from solid to liquid.

Front

What is conduction?

Back

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