Properties of Water Assessment

Front

What effect does increasing salinity have on the boiling point of water?

Back

It increases the boiling point.

Front

What phenomenon is responsible for water's ability to transport nutrients in plants?

Back

Capillary action.

Front

Which property of water allows it to dissolve many substances?

Back

Polarity.

Front

Why does ice float on water?

Back

It is less dense than liquid water.

Front

What is the main reason for water's high boiling point compared to other similar molecules?

Back

Hydrogen bonding.

Front

Define cohesion in the context of water properties.

Back

Cohesion is the attraction between molecules of the same substance, which in water leads to surface tension.

Front

Define adhesion in the context of water properties.

Back

Adhesion is the attraction between molecules of different substances, allowing water to stick to surfaces.

Front

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

Back

It allows water to absorb and release heat without significant temperature changes, stabilizing climates and environments.

Front

Explain the concept of density in relation to water and ice.

Back

Ice is less dense than liquid water, which is why it floats; this is due to the arrangement of water molecules in solid form.

Front

What role do hydrogen bonds play in the properties of water?

Back

Hydrogen bonds are responsible for water's high boiling point, surface tension, and solvent capabilities.
