Amplify Thermal Energy C2 Flashcard

Front

What happens when two objects collide in terms of thermal energy?

Back

The warmer object transfers its energy to the cooler object.

Front

How does kinetic energy transfer occur between two objects in contact?

Back

Kinetic energy transfers from fast-moving molecules to slower-moving molecules.

Front

Why does red food coloring mix faster than blue food coloring in hot water?

Back

The red food coloring is in the hot water.

Front

What occurs when a frozen Bubba-Burger is placed on a hot grill?

Back

The grill molecules are transferring energy to the Bubba-Burger.

Front

What is the average kinetic energy of molecules in a sample?

Back

It is a measure of the energy of motion of the molecules.

Front

Define thermal energy.

Back

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

Front

What is kinetic energy?

Back

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

Front

Explain the concept of thermal equilibrium.

Back

Thermal equilibrium occurs when two objects in contact reach the same temperature and no heat flows between them.

Front

What is the relationship between temperature and kinetic energy?

Back

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

Front

What is conduction?

Back

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