Front

Why do molecules move slower in cold water?

Back

Because the temperature is lower, resulting in decreased kinetic energy.

What are three examples of liquids?

Back

Juice, milk, water

Front

What is the definition of evaporation?

Back

The process by which molecules transition from the liquid phase to the gas phase.

Front

What factors affect the rate of evaporation?

Back

Temperature, humidity, surface area, and air movement.

Front

How does temperature affect the movement of molecules in different states of matter?

Back

Higher temperatures increase molecular movement, while lower temperatures decrease it.

Front

What is the difference between a solid, liquid, and gas in terms of molecular arrangement?

Back

Solids have closely packed molecules, liquids have loosely packed molecules, and gases have widely spaced molecules.

Front

What happens to the kinetic energy of molecules as a substance changes from solid to liquid?

Back

The kinetic energy increases, allowing molecules to move more freely.
