1.1 Properties of Water/ Hydrogen Bonding

Front

What is capillary action?

Back

Capillary action is the ability of water to move through narrow spaces against gravity, due to the cohesive forces between water molecules and the adhesive forces between water and the surrounding material.

Front

What is the significance of hydrogen bonds in water?

Back

Hydrogen bonds are weak attractions between the hydrogen atom of one water molecule and the oxygen atom of another, which contribute to water's unique properties, such as cohesion and high heat capacity.

Front

Define cohesion in the context of water.

Back

Cohesion is the property of water molecules to stick to each other due to hydrogen bonding, which is responsible for phenomena like surface tension.

Front

Define adhesion in the context of water.

Back

Adhesion is the property of water molecules to stick to other substances, which helps water to move through plant tissues.

Front

What is high heat capacity?

Back

High heat capacity refers to water's ability to absorb and retain heat without a significant change in temperature, which helps regulate climate and maintain stable environments.

Front

What is the process of condensation?

Back

Condensation is the process by which water vapor (gas) cools and changes into liquid water, often forming clouds or dew.

Front

What is the difference between evaporation and condensation?

Back

Evaporation is the process of liquid water turning into vapor, while condensation is the process of vapor turning back into liquid.

Front

What type of bond is formed between hydrogen and oxygen in water?

Back

Water molecules are formed by polar covalent bonds, where electrons are shared unequally between hydrogen and oxygen.

Front

Why does water have a high boiling point compared to other similar molecules?

Back

Water has a high boiling point due to the strong hydrogen bonds between its molecules, which require more energy to break.

Front

What role does water play as a solvent?

Back

Water is known as a universal solvent because it can dissolve many substances, facilitating chemical reactions and biological processes.
