What is the molecular formula for water?

Back

H₂O

Front

What property of water allows it to form hydrogen bonds?

Back

Polarity

Front

What is cohesion in the context of 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 the context of water?

Back

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

Front

What is capillary action?

Back

Capillary action is the ability of water to flow in narrow spaces without the assistance of external forces, due to cohesion and adhesion.

Front

What is surface tension?

Back

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

Front

Why does ice float on water?

Back

Ice floats on water because it is less dense than liquid water due to the arrangement of hydrogen bonds in the solid state.

Front

What is specific heat?

Back

Specific heat is the amount of heat required to raise the temperature of a substance by one degree Celsius.

Front

How does water's high specific heat benefit the environment?

Back

Water's high specific heat helps regulate temperature in the environment, preventing drastic temperature changes.

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 specific heat, cohesion, and surface tension.
