Review Water Properties

Front

What is the specific heat of water?

Back

Water has a high specific heat, meaning it can absorb a lot of heat before its temperature changes significantly.

Front

How does water regulate body temperature?

Back

Water absorbs a lot of heat, but only increases a little in temperature, helping to cool the body through sweating.

Front

What happens to organisms if water had a low specific heat?

Back

Organisms that are sensitive to changes in temperature would die.

Front

Why do large bodies of water not fluctuate in temperature quickly?

Back

Large bodies of water have a high heat capacity, which allows them to absorb and retain heat.

Front

What part of a water molecule has a negative charge?

Back

The Oxygen atom has a negative charge.

Front

Why does ice float on water?

Back

Ice floats because water expands when it freezes, making ice less dense than liquid water.

Front

What is the role of hydrogen bonds in water?

Back

Hydrogen bonds create cohesion and surface tension in water, allowing it to form droplets.

Front

What is the significance of water being a polar molecule?

Back

Water's polarity allows it to dissolve many substances, making it an excellent solvent.

Front

How does water's high heat capacity benefit aquatic ecosystems?

Back

It helps maintain stable temperatures in aquatic environments, protecting organisms from temperature fluctuations.

Front

What is the effect of water's high specific heat on climate?

Back

It moderates climate by absorbing heat during the day and releasing it at night.
