Water Characteristics

Density of pure water is

• 1 g cm-³

• 10 g cm-³

• 13 g cm-³

When we add salt into pure water, the boiling point of the solution will

• be more than the pure water boiling point.

• be less than the pure water boiling point.

• same as the pure water boiling point.

Insects like daddy longlegs can move on the surface of the water because of

• water has higher density than insects.

• water is heavier than the insects.

• water has high surface tension.

What is the name of the phenomenon than make the water moves from the bottom to the leaves?

• Conduction action

• Capillary action

• Transpiration

• Translation

The rate of evaporation is high when

• humidity is high

• small exposed surface area of water

• surrounding temperature is low

• exposed to the wind

• melting point

• freezing point

• boiling point

• density
