Properties of Water - part 1

Front

What percent of Earth's surface is covered by water?

Back

71%

Front

True or False: Hydrogen bonds between water molecules give water a high level of cohesion.

Back

True

Front

What property of water enables it to interact with other polar substances?

Back

Polarity

Front

What property of water do plants use to move water upward from their roots to their leaves?

Back

Capillary action

Front

What type of bonds exist between two water molecules?

Back

Hydrogen

Front

Define cohesion in the context of water.

Back

Cohesion is the attraction between water molecules due to hydrogen bonding, which allows water to form droplets and maintain surface tension.

Front

Define adhesion in the context of water.

Back

Adhesion is the attraction between water molecules and other substances, which allows water to climb up surfaces, such as in capillary action.

Front

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

Back

Water's high specific heat allows it to absorb and release large amounts of heat without significant temperature changes, helping to regulate climate and maintain stable environments.

Front

Explain the concept of surface tension in water.

Back

Surface tension is the cohesive force at the surface of water that makes it behave like a stretched elastic membrane, allowing small objects to float.

Front

What is the role of water's polarity in biological systems?

Back

Water's polarity allows it to dissolve many substances, making it an excellent solvent for biochemical reactions in living organisms.
