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.
Matter anything that has mass and takes up space
Mass the amount of material that an object has in it
Volume the amount of space that matter takes up
Mixture two or more substances that are mixed together but can be easily separated
Solution a mixture in which one substance spreads evenly throughout another substance
Meter a unit for measuring length
Cubic meter a unit for measuring the volume of a solid
Liter a unit for measuring volume
Graduated cylinder a tool used to measure the volume of liquids
Gram the basic unit for measuring mass
Density how much mass is in a certain volume of matter
Physical change a change in matter that changes physical properties but does not produce a different kind of matter
Melting point the temperature at which matter changes from a solid to a liquid
Boiling point the temperature at which matter changes from a liquid to a gas
Freezing point the temperature at which matter changes from a liquid to a solid
Chemical change a change in matter that produces a different kind of matter
