REDIRECT Unit Review #3 (Chemistry of Water)

Front

What causes water droplets to form on the outside of a cold glass?

Back

The cold liquid in the glass cools the air around it, causing water vapor to condense into a liquid.

Front

Which greenhouse gas enters our atmosphere through evaporation?

Back

Water.

Front

What happens to the molecules of a substance at higher temperatures?

Back

Energy increases, causing molecules in the substance to move faster and become less dense.

Front

What occurs when water boils and escapes as steam?

Back

The molecules speed up as the kinetic energy increases and the molecules move farther apart from one another.

Front

What is the pH of baking soda?

Back

9.

Front

What is the pH of bleach?

Back

12.

Front

What can be said about the relationship between baking soda and bleach based on their pH levels?

Back

Both solutions are bases.

Front

What is condensation in the context of water vapor?

Back

The process where water vapor cools and changes into liquid water.

Front

What is evaporation?

Back

The process where liquid water changes into water vapor.

Front

Define kinetic energy in relation to molecules in a substance.

Back

Kinetic energy is the energy of motion; as temperature increases, kinetic energy increases, causing molecules to move faster.
