Why can a water strider skate on the surface of water?

Back

Hydrogen bonds result in water cohesion (surface tension).

Front

What is adhesion in the context of water?

Back

Water's ability to stick to other substances.

Front

What causes water molecules to stick together?

Back

One side has a positive charge and the other side has a negative charge.

Front

Which substance can water NOT dissolve?

Back

Oil.

Front

What is cohesion in relation to water?

Back

The attraction between water molecules due to hydrogen bonding.

Front

What is surface tension?

Back

The cohesive force at the surface of a liquid that makes it behave like a stretched elastic membrane.

Front

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

Back

It allows water to absorb a lot of heat without a significant change in temperature, stabilizing climates.

Front

What is the role of hydrogen bonds in water?

Back

They create a strong attraction between water molecules, leading to unique properties like cohesion and adhesion.

Front

How does temperature affect the density of water?

Back

Water is most dense at 4°C; as it freezes, it becomes less dense, which is why ice floats.
