Physical and Chemical Properties Physical Science Physical and Chemical Properties

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

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.

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 ____________ ____________ _______________.

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

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.

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.

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.

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

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.

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

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

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.

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

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

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

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

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. .

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.
