Properties of Water and Their Effects

Very light insects can sit on top of water because of

• Water's High Heat of Vaporization

• Surface Tension

• Water's High Specific Heat

• Capillary Action

What makes water a universal solvent?

• It is a polar molecule that can form hydrogen bonds, allowing it to dissolve many substances.

• It is a nonpolar molecule that can form hydrogen bonds, allowing it to dissolve many substances.

• It is a polar molecule with a low specific heat, allowing it to dissolve many substances.

• It is a nonpolar molecule with a low specific heat, allowing it to dissolve many substances.

When it rains, water will stick to your clothes and get them wet. What property is this an example of?

• Cohesion

• Adhesion

• High Specific Heat Capacity

• Surface Tension

What is this an example of: Earth's temperatures are mostly stable because of water.

• Water's low density

• Water's high heat capacity

• Water's super solvency

• Water's polarity

Why do the molecules on the surface of a body of water stick together to create surface tension?

• Cohesion - the water sticks together.

• Adhesion - the water sticks together.

• Low-density solid - the ice is there.

• Super solvency - there are dissolved molecules in it.

This is surface tension holding up an insect. Surface tension is caused by (a)   of water molecules at the top of the water.

Capillary action is when a plant drinks water up through its roots.

What causes the water to stick to the plant roots?

(a)  

Water is a universal solvent because it...

• It can be found anywhere
• It freezes when it gets cold
• floats when frozen
• Dissolves most substances

A water molecule has the chemical formula H2O. This means that the water molecule is made up of

• Two hydrogen atoms and one oxygen atom

• Two oxygen atoms and one hydrogen atom

• Two hydrogen atoms and two oxygen atoms

• Two molecules of water

As you added drops to the coins, each drop stuck to the other water because of ________________.

• adhesion
• cohesion
• capillary action
• specific heat
