MM 2.6 Law of Conservation of Matter

When solid water (ice) melts and becomes liquid water - what is happening to the molecules of the water?

The diagram above shows ice cubes before and after they melt. Which answer is most likely to be true?

Physical and Chemical Changes

MASS is the amount of matter in an object or substance. Today, we will measure mass in grams ( g ).

A physical change is a change in size, shape, or state of matter that does NOT create a new substance.

A chemical change is a change that occurs to matter and a new substance is created.
