• False

What is water made of?

• Water
• Liquid
• Hydrogen and oxygen
• Blue 

Which end of the water molecule has a slightly positive charge?

• the oxygen end
• the hydrogen end
• both ends are slightly positive
• neither end is positive

Used to describe a molecule that has an unequal distribution of charges (positive and negative)

• non polar

• element

• polar

• chemicals

A weak bond formed by the attraction of more positively charged H on one molecule and the more negatively charged O (or N or F) on a different molecule.

• ionic

• covalent

• hydrogen

Refer to the picture of water sticking to a leaf; this is occurring because of:

• Adhesion

• Cohesion

Describe COHESION.

• Water molecules attracted to other substances.

• Water molecules climbing upwards against the force of gravity.

• Water molecules dissolving many substances because of its polarity.

• Water molecules attracted to other water molecules.

What word describes when water is attracted to other substances?

• cohesion
• adhesion
• capillary action
• surface tension

molecule in which opposite ends have opposite electric charges

• cohesion
• polar molecule
• hydrogen bond
• solution

Water's ability to stick to glass is

• adhesion

• cohesion

• surface tention

• capillary action
