Water is considered a polar molecule because

• it is attracted to the north pole

• it has a positively charged end and a negatively charged end

• it is attracted to metal poles

• it repels other substances

When water molecules stick to other water molecules, this is called -

• cohesion

• adhesion

• surface tension

• capillary action

A water molecule has -

• two positively charged hydrogen and oxygen ends

• positively charged hydrogen ends and a negatively charged oxygen end.

• two negatively hydrogen and oxygen ends

• negatively charged hydrogen ends and a positively charged oxygen end.

This is the tightness across the surface of water caused by polar molecules pulling on each other.

• cohesion

• adhesion

• capillary action

• surface tension

This is the amount of heat needed to increase the temperature of a certain mass of a substance by 1 degree

• cohesion

• adhesion

• capillary action

• specific heat
