Amplify Thermal Energy C2 Flashcard

Front

What happens when a 65 degree sample makes contact with a 35 degree sample?

Back

The 65 degree sample will get hotter with energy from the 35 degree sample until they reach thermal equilibrium.

Front

How do molecules behave when an object gets colder?

Back

The molecules move slower.

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 if it is given as 3?

Back

The average kinetic energy of the molecules is 3.

Front

At what temperature will a 65 degree sample and a 35 degree sample reach equilibrium?

Back

They will reach equilibrium at 50 degrees.

Front

Define thermal equilibrium.

Back

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

Front

What is thermal energy?

Back

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

Front

Explain the concept of heat transfer.

Back

Heat transfer is the movement of thermal energy from a hotter object to a cooler one.

Front

What is conduction?

Back

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

Front

What is convection?

Back

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