Water Properties Unit 3

Front

What is the bond that forms between two molecules of water?

Back

Hydrogen Bonding

Front

What is the heat(energy) required to create a phase change without a change in temperature?

Back

Latent Heat

Front

Which of the following is an example of COHESION?

Back

Water sticking to water.

Front

A water spider can skate along the top of a pond because:

Back

Hydrogen bonds result in water cohesion (surface tension).

Front

The property of water that allows water molecules to stick to another substance is:

Back

Adhesion.

Front

Define Hydrogen Bonding.

Back

A weak bond between two molecules resulting from an electrostatic attraction between a proton in one molecule and an electronegative atom in the other.

Front

What is Latent Heat?

Back

The amount of heat required to change a substance from one phase to another without changing its temperature.

Front

Explain Cohesion in water.

Back

Cohesion is the attraction between water molecules, which allows them to stick together, contributing to surface tension.

Front

What is Adhesion in the context of water?

Back

Adhesion is the attraction between water molecules and other substances, allowing water to spread on surfaces.

Front

What is Surface Tension?

Back

The property of the surface of a liquid that allows it to resist an external force, due to cohesive forces between liquid molecules.
