In the cold cup test, which cup kept the water cold better?

Back

The fancy cup kept the water cold better than the regular cup.

Front

What state of matter has particles that are loosely packed and can move around?

Back

Liquid.

Front

How does the number of particles in contact affect energy transfer?

Back

The greater the number of particles in contact, the greater the amount of kinetic energy is transferred from the warmer piece of matter to the cooler pieces.

Front

Which image would show faster energy transfer?

Back

Image A shows faster energy transfer.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance, related to its temperature.

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).

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves, such as light.

Front

What happens to the temperature of a substance when it absorbs thermal energy?

Back

The temperature of the substance increases.
