A teacher pours 55mL of cooking oil into a graduated cylinder. He then pours in 35 mL of water and lets the mixture sit for 30 minutes.

What will most likely happen to the liquids in the graduated cylinder?

The oil will remain on the bottom because there is more of it.

The oil will mix with the water and form a solution.

The oil will rise to the top because it is less dense than water.

The oil will remain on the bottom because it was poured in first.

Which property of matter is best illustrated by this image?

Magnetic objects will be pulled toward or away from a magnet.

Matter is made of particles that are too small to be seen.

Materials with a relative density less than water will float.

Matter changes state when it is heated or cooled.

A glass of water was left outside over a period of five days.

What caused the level of water in the glass to decrease each day?

Heat over time caused the water to evaporate.

Colder temperatures changed the water from liquid to solid.

Melting caused less liquid to appear in the glass.

Heat caused the water to boil.
