A water molecule has a slightly positive end and a slightly negative end which means that water is a

• negative molecule

• polar molecule

• non-polar molecule

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

• the oxygen

• the hydrogen

The attraction of water molecules to other water molecules is known as

• adhesion

• surface tension

• cohesion

Ice floats on water. This is because

• ice is more dense than water

• ice is less dense than water

What property of water creates surface tension?

• High specific heat

• adhesion

• cohesion

• density
