VCS Biology _ Unit 1_Properties of Water

Front

Why does ice stay at the top of oceans instead of sinking to the bottom?

Back

Ice is less dense than liquid water.

Front

What type of bond is indicated by the #1?

Back

Hydrogen bond.

Front

What unique property of water allows fish and aquatic plants to survive a cold winter?

Back

Water expands and becomes less dense when it freezes.

Front

Which property of water makes it good at regulating temperature?

Back

Water has a high capacity for heat.

Front

What is the charge of oxygen in a water molecule?

Back

Negative.

Front

Define density in the context of water.

Back

Density is the mass of water per unit volume; ice is less dense than liquid water.

Front

What is a hydrogen bond?

Back

A weak bond formed between a hydrogen atom and an electronegative atom, such as oxygen.

Front

Explain the significance of water's high specific heat capacity.

Back

It allows water to absorb and retain heat, stabilizing temperatures in organisms and environments.

Front

What is cohesion in relation to water?

Back

Cohesion is the attraction between water molecules, leading to surface tension.

Front

What is adhesion in relation to water?

Back

Adhesion is the attraction between water molecules and other substances.
