Properties of Water

Front

What is the property of water that allows it to dissolve many substances?

Back

Water is known as the 'Universal Solvent' because it can dissolve more substances than any other liquid.

Front

What happens to water when it freezes?

Back

When water freezes, it expands and its density decreases, which is why ice floats on water.

What is cohesion in relation to water?

Back

Cohesion is the property of water that allows water molecules to stick to each other, creating surface tension.

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 glass.

Why do small insects like water striders walk on water?

Back

Small insects can walk on water because they are light enough not to break the hydrogen bonds between water molecules.

Front

What is surface tension?

Back

Surface tension is the elastic-like force existing on the surface of a body of liquid, caused by the attraction of the liquid's molecules.

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 before its temperature changes, helping to regulate climate and body temperature.

What is the pH level of pure water?

Back

The pH level of pure water is 7, which is considered neutral.

Front

What is the difference between polar and nonpolar molecules?

Back

Polar molecules have a partial positive charge on one side and a partial negative charge on the other, while nonpolar molecules do not have charged ends.

Front

What is the role of hydrogen bonds in water?

Back

Hydrogen bonds are weak attractions between water molecules that contribute to water's unique properties, such as cohesion and high surface tension.
