Water Properties

Front

What is surface tension?

Back

Surface tension is the tightness across the surface of water that allows objects, like paper clips, to float.

Front

What is cohesion in the context of water?

Back

Cohesion refers to the attraction between water molecules, exemplified by water sticking to water.

Front

What does it mean for a molecule to be polar?

Back

A polar molecule has a positive end and a negative end, like water (H2O).

Front

Why does ice float on water?

Back

Ice floats because water expands when it freezes, making ice less dense than liquid water.

Front

Is water the universal solvent?

Back

False, water is not the universal solvent; it dissolves many substances but not all.

Front

What is adhesion?

Back

Adhesion is the attraction between water molecules and other substances, such as water sticking to glass.

Front

What is capillary action?

Back

Capillary action is the ability of water to flow in narrow spaces without the assistance of external forces, often seen in plants.

Front

What role do hydrogen bonds play in water's properties?

Back

Hydrogen bonds are responsible for many of water's unique properties, including its high surface tension and boiling point.

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.

Front

How does water's density change when it freezes?

Back

Water's density decreases when it freezes, which is why ice floats on liquid water.
