Properties of Water

Front

Why does ice float on water?

Back

Ice floats on water because it is less dense than liquid water due to the expansion of water molecules when they freeze.

Front

What is the reason ice remains on the surface of oceans?

Back

Ice remains on the surface of oceans because it is less dense than liquid water.

Front

What is a polar molecule?

Back

A polar molecule is a molecule that has an opposite electrical charge on each end, resulting in a positive and a negative pole.

Front

What two elements combine to form water?

Back

Water is composed of two elements: hydrogen and oxygen.

Front

What property of water allows large bodies to maintain stable temperatures?

Back

Water has a high heat capacity, which allows large bodies of water to resist rapid temperature changes.

Front

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

Back

Water's high heat capacity helps regulate climate by absorbing and storing heat, preventing extreme temperature fluctuations.

Front

How does the density of ice compare to that of liquid water?

Back

Ice is less dense than liquid water, which is why it floats.

Front

What is the molecular structure of water?

Back

Water has a bent molecular structure with one oxygen atom bonded to two hydrogen atoms.

Front

Why is water considered a universal solvent?

Back

Water is considered a universal solvent because it can dissolve many substances due to its polar nature.

Front

What role does hydrogen bonding play in the properties of water?

Back

Hydrogen bonding contributes to water's high surface tension, high heat capacity, and unique density properties.
