Physical and Chemical Properties

2. physical properties
A ___________ ______________ is something that can be observed about an object without changing the identity of the object.

3. Density, color, odor, hardness, magnetism
2. Physical properties of matter such as, mass, volume, and weight can describe the amount of matter. ___________,
____________, ______________, ________________ and
______________ are some other physical properties.

4. Mass, equal pan balance
3.___________ is the amount of matter in an object. Mass is measured in kilograms (kg) or grams (g). Mass can be measured using an ____________ ____________ _______________.

5. Weight, Newtons
4. ____________ is how strongly gravity pulls on an object.
Weight is measured in ___________(N) using a spring scale.

6. Volume, length, width, height
5. ______________ measures how much space matter takes up.
You can calculate the volume of a regularly shaped object,
such as a rectangle by multiplying the object’s __________ by
its ___________ by its __________: L x W x H = volume.

7. graduated cylinder
6. Irregular shaped objects are placed in a ____________ __________________ with water in it which raises the water level. The change in the water level when an object is placed in it tells us the object’s volume.

8. cubic centimeters (cm³), milliliters (mL)
7. The volume of a solid is usually measured in cubic centimeters, while liquid volume is often measured in milliliters.

9. Density
8. ___________ is the amount of mass for each cubic centimeter or milliliter of a substance. To calculate a sample’s density, you divide its mass by its volume.
Density = mass
volume

10. Buoyancy 9. ________________ is the resistance to sinking which occurs
because the liquid that is being pushed out of the way pushes
back on the object.

11. density 10. Buoyancy depends on ______________. If you change the
mass or volume of an object, you can change whether it will float.

12. chemical property
11. A _________________ describes the way a substance reacts
with other substances.

13. Flammability
12. Hydrogen can be described as being flammable. ____________________is a chemical property of a substance that describes its ability to catch fire or burn.

14. Corrosion
13. When left outside, some metals will corrode. _____________ is when metals combine with nonmetals from the environment.

15. extensive, intensive
14. Physical properties can be classified into two types:
____________ and ____________ properties.

16. amount, mass, volume, weight
15. Extensive properties depend on the ___________ of substance present. Examples of extensive properties includes ___________, _____________, and ______________.

17. Density
16. Intensive properties do not depend on the amount of substance present. _____________ is an intensive physical property.

18. boiling point
17. The temperature at which a substance boils is a physical
property called its ____________ _______________. The boiling point of water is 212°F. THe boiling point of a substance does not depend on the mass of the substance, so it is an intensive property. .

19. freezing point
18. A substance’s ______________ _______________ is the temperature at which it freezes. Water, for example, freezes at 32°F regardless of how much water there is.
