Water Properties

Front

What is water's high heat capacity?

Back

Water's high heat capacity means it can absorb a lot of heat before its temperature rises significantly, helping to regulate temperature in the environment and in living organisms.

Front

What are hydrogen bonds?

Back

Hydrogen bonds are weak attractions between the negative oxygen atom of one water molecule and the positive hydrogen atom of another water molecule.

Front

What is cohesion in water?

Back

Cohesion is the property of water that allows water molecules to stick together, which is responsible for surface tension.

Front

What is adhesion in water?

Back

Adhesion is the property of water that allows it to stick to other substances, which helps in processes like capillary action.

Front

What is the significance of water's polarity?

Back

Water's polarity allows it to dissolve many substances, making it an excellent solvent for chemical reactions in biological systems.

Front

What is surface tension?

Back

Surface tension is the cohesive force at the surface of water that makes it behave like a stretched elastic membrane.

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.

Front

What is the role of water in temperature regulation?

Back

Water helps regulate temperature in organisms and environments due to its high heat capacity and ability to absorb heat.

Front

What is the difference between covalent bonds and hydrogen bonds in water?

Back

Covalent bonds are strong bonds that hold the hydrogen and oxygen atoms together within a water molecule, while hydrogen bonds are weaker attractions between water molecules.

Front

What is the importance of water as a solvent?

Back

Water's ability to dissolve many substances makes it essential for biochemical reactions and transport of nutrients in living organisms.
