Chapter 1B Measuring Matter

1. What is Matter?

Mass is the amount of material in matter, and volume is the amount of space that matter takes up.

A property is something about matter that can be observed and tells you what the matter is like.

Matter can be mixed together in solutions and other mixtures.

2. How are length and volume measured?

Length is measured in meters.

Volume is measured in cubic meters or liters.

3. How do you find mass and density?

The metric system uses gram, milligram, and kilogram to measure mass.

Density is how much mass is in a certain volume of matter.

4. What are physcial changes?

A physical change is a change in size, shape, color, or state of matter.

Heating and cooling cause physcial changes in matter.

5. What are chemical changes?

A chemical change produces a completely different kind of matter.

Rusing, tarnishing, and burning are chemical changes of matter.
