Fast and Curious Gr 7 Science Fusion Unit Earth's Water Lesson 1

When a molecule has an opposite electrical charge on each end, it is known as what?

• cohesion
• polar molecule
• hydrogen bond
• solution

What word describes when water is attracted to other substances?

• cohesion
• adhesion
• capillary action
• surface tension

When water molecules stick easily to other water molecules, this is called what?

• cohesion
• adhesion
• solution
• polar molecule

Water is a universal solvent because it...

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

• it dissolves most substances

Water molecules require a lot of energy to separate one from the others.  This gives water a high

• density
• polarity
• solvency
• specific heat
