On a hot, summer day, water droplets often form on the outside of a cold glass of water. The water droplets form when water vapor in the air

• loses heat on the cold glass

• reacts with the chemicals in the air

• gains energy from sunlight

• is moved about quickly by wind

After taking a shower, a student observed water droplets condensing on the bathroom mirror. Water condenses on the mirror because the mirror -

• reflects light energy

• is cooler than the air

• is a large, flat solid

• can easily be removed

The following are physical characteristics of pure water except...

• low surface tension

• _colourless

• tasteless

• liquid at room temperature

When water freezes in the ocean, the ice floats to the surface. What property explains this phenomenon?

• water expands when it freezes, making ice less dense than water

• water compacts when it freezes, making ice more dense than water

• hydrogen bonds in water push the ice to the surface

• ice is afraid of water, and avoids it
