Properties of Water

Front

What is the specific heat of water?

Back

Specific heat is the amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius. Water has a high specific heat, which helps stabilize temperatures in aquatic environments.

Front

What is cohesion in relation to water?

Back

Cohesion is the property of water molecules to stick to each other due to hydrogen bonding. This property contributes to water's surface tension.

Front

Why is water known as the Universal Solvent?

Back

Water is called the Universal Solvent because its polarity allows it to dissolve many ionic and polar substances, making it essential for biological processes.

Front

What is the solvent power of water?

Back

Solvent power refers to water's ability to dissolve various substances, which is crucial for chemical reactions in living organisms.

Front

What role does evaporation play in temperature regulation?

Back

Evaporation is the process where water molecules transition from liquid to gas, which helps cool organisms as they lose heat during this process.

Front

What is surface tension?

Back

Surface tension is the elastic tendency of a fluid surface that makes it acquire the least surface area possible. In water, it is caused by cohesive forces between water molecules.

Front

How does adhesion differ from cohesion?

Back

Adhesion is the attraction between water molecules and other substances, while cohesion is the attraction between water molecules themselves.

Front

What is the significance of water's high heat capacity?

Back

Water's high heat capacity allows it to absorb and store large amounts of heat without significant changes in temperature, which is vital for climate regulation.

Front

What is the impact of water's polarity on its properties?

Back

Water's polarity leads to hydrogen bonding, which is responsible for many of its unique properties, including high specific heat, surface tension, and solvent capabilities.

Front

How does water's density change with temperature?

Back

Water is unique in that it is less dense as a solid (ice) than as a liquid, which allows ice to float and insulates bodies of water.
