Properties of Water and Water Cycle

Front

What is surface tension?

Back

Surface tension is the property of a liquid that allows it to resist an external force, due to the cohesive nature of its molecules. It enables insects like water striders to skate on water.

Front

What is adhesion in the context of water?

Back

Adhesion is the attraction between water molecules and other substances. It allows water to climb up plant roots and stems.

Front

What are the three states of water?

Back

Water naturally exists in three states: solid (ice), liquid (water), and gas (water vapor).

Front

Why does ice float on water?

Back

Ice is less dense than liquid water, which is why it floats. This property protects aquatic life by insulating the water below.

Front

What is specific heat capacity?

Back

Specific heat capacity is the amount of heat required to raise the temperature of a substance. Water has a high specific heat capacity, which helps moderate Earth's climate.

Front

What is cohesion in water?

Back

Cohesion is the attraction between water molecules. It causes water to form droplets and is responsible for surface tension.

Front

What is capillary action?

Back

Capillary action is the ability of water to flow in narrow spaces against gravity, due to adhesion and cohesion. It helps water move through soil and plant roots.

Front

What is the water cycle?

Back

The water cycle is the continuous process by which water evaporates, condenses, and precipitates back to Earth, involving processes like evaporation, condensation, and precipitation.

Front

What role does water play in temperature regulation?

Back

Water helps regulate temperature due to its high specific heat capacity, absorbing and releasing heat slowly, which stabilizes temperatures in the environment.

Front

What is latent heat of vaporization?

Back

Latent heat of vaporization is the amount of energy required to convert water from liquid to gas without changing its temperature. This process cools the environment.
