Properties of Water Review Game

Front

What is hydrogen bonding in water?

Back

Hydrogen bonding in water refers to the attraction between the positively charged hydrogen atoms of one water molecule and the negatively charged oxygen atom of another water molecule. This interaction is responsible for many of water's unique properties.

Front

What is specific heat?

Back

Specific heat is the amount of heat required to raise the temperature of a substance by one degree Celsius. Water has a high specific heat, meaning it can absorb a lot of heat without a significant change in temperature.

Front

Why is water's high specific heat important for aquatic life?

Back

Water's high specific heat helps to stabilize temperatures in aquatic environments, preventing drastic temperature changes that could harm sensitive organisms.

Front

What happens to water when it freezes?

Back

When water freezes, it expands and becomes less dense, which is why ice floats on liquid water.

Front

What is the significance of ice floating on water?

Back

Ice floating on water insulates the water below, allowing aquatic life to survive in cold conditions by preventing the entire body of water from freezing solid.

Front

Define cohesion in the context of water.

Back

Cohesion is the property of water molecules to stick to each other due to hydrogen bonding, which contributes to phenomena like surface tension.

Front

Define adhesion in the context of water.

Back

Adhesion is the property of water molecules to stick to other substances, which allows water to climb up plant roots and stems through capillary action.

Front

What is capillarity?

Back

Capillarity is the ability of water to flow in narrow spaces without the assistance of external forces, due to the combination of cohesion and adhesion.

Front

What is an acid in terms of pH?

Back

An acid is a substance that increases the hydrogen ion (H+) concentration in a solution, with a pH of 6.9 or below.

Front

What is a base in terms of pH?

Back

A base is a substance that decreases the hydrogen ion (H+) concentration in a solution, typically having a pH above 7.
