How does the temperature of the top wooden cube compare to the bottom cube before they touch?

Back

The bottom cube is hotter than the top cube.

Front

What happens to the temperature of the top cube when it touches the bottom cube?

Back

The cooler top cube will gain kinetic energy until both cubes reach the same temperature.

Front

What happens to the motion of molecules when the temperature is decreased?

Back

The motion of molecules decreases.

Back

False.

Front

What is thermal energy?

Back

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

Front

What is the relationship between temperature and kinetic energy?

Back

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

Front

What is conduction?

Back

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

Front

What is convection?

Back

Convection is the transfer of thermal energy through the movement of fluids (liquids and gases).
