The air molecules gained energy from the warm water, increasing their temperature.

The air molecules lost energy to the water, decreasing their temperature.

The temperature change was caused by the cup itself, not the water.

The temperature change was due to an external heat source not shown in the image.

Molecules gain energy and move faster.

Molecules lose energy and move slower.

Molecules stay at the same speed regardless of temperature.

Molecules disappear when heated.

The speed of molecules

The color of molecules

The size of molecules

The number of molecules

Kinetic energy

Potential energy

Thermal energy

Chemical energy

When a thing gets hotter, its molecules move faster and have more kinetic energy.

When a thing gets colder, its molecules move slower and have less kinetic energy.

Kinetic energy is only present in hot objects.

Molecules do not have kinetic energy.

The average kinetic energy

The total number of molecules

The color of the substance

The amount of light emitted

Hot water has faster moving molecules.

Cold water has slower moving molecules.

Hot water has less kinetic energy than cold water.

Cold water has more kinetic energy than hot water.

The average kinetic energy of molecules increases as temperature rises.

The average size of molecules increases as temperature rises.

The average number of molecules increases as temperature rises.

The average color of molecules changes as temperature rises.
