What is the reason water molecules stick together?

Back

Water molecules stick together because one side has a positive charge and the other side has a negative charge.

Front

Why can water striders walk across the surface of water without falling through?

Back

Water striders can walk across the surface of water because they are light enough not to break the hydrogen bonds holding the water molecules together.

Front

What makes water a universal solvent?

Back

The part that gets dissolved in a solution is called the solute.

Front

What is cohesion in relation to water?

Back

Cohesion is the property of water that allows water molecules to stick to each other due to hydrogen bonding.

Front

What is adhesion in relation to water?

Back

Adhesion is the property of water that allows it to stick to other substances.

Front

What is the significance of water's high specific heat?

Back

Water's high specific heat allows it to absorb and release large amounts of heat without significantly changing temperature, which helps regulate climate.

Front

What is surface tension in water?

Back

Surface tension is the cohesive force at the surface of water that makes it behave like a stretched elastic membrane.

Front

What is the pH level of pure water?

Back

The pH level of pure water is 7, which is considered neutral.
