Properties of Water

Front

What is cohesion in relation to water?

Back

Cohesion is the property of water that allows water molecules to stick to each other, which is why water forms droplets.

Front

What is adhesion in relation to water?

Back

Adhesion is the property of water that allows it to stick to other substances, such as when water climbs up a paper towel.

Front

Which end of the water molecule has a slightly negative charge?

Back

The oxygen end of the water molecule has a slightly negative charge.

Front

What does it mean for a membrane to be selectively permeable?

Back

What is capillary action?

Back

Capillary action is the ability of water to move through narrow spaces, such as in plants, allowing water to travel from roots to leaves.

Front

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

Back

Water's high specific heat means it can absorb a lot of heat without a significant change in temperature, helping to regulate climate.

What is the hydrophobic region of a cell membrane?

Back

The hydrophobic region of a cell membrane is the part that repels water, helping to form a barrier that separates the inside of the cell from the outside.

Front

What is surface tension in water?

Back

Surface tension is the property of water that allows it to resist external force, due to the cohesive nature of its molecules.

Front

How does water's density change when it freezes?

Back

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