Chapter 1 NotesSection 2+3

Physical Properties(characteristics)
can be observed or measured without
changing the object
![Page 3: Chapter 1 Notes](https://reader036.fdocuments.us/reader036/viewer/2022070400/56812cfe550346895d91d4ce/html5/thumbnails/3.jpg)
Examples:
1. Color
2. Odor
3.Thermal conductivity – ability to transfer heat
![Page 4: Chapter 1 Notes](https://reader036.fdocuments.us/reader036/viewer/2022070400/56812cfe550346895d91d4ce/html5/thumbnails/4.jpg)
4. Solubility ability to dissolve
5. Malleability – ability to be pounded into thin sheets
6. Ductility – ability to be pulled into thin wires

7.Density mass per unit volume Density is the same for the same
substance
Density of one substance is usually different than the density of other substances

Formula to calculate density: D = M Density = Mass (g) V Volume (mL)
The density of pure water is 1 g/mL

A substance with a density greater than water sinks in water
A substance with a density less than water floats in water

Chemical Properties arebased on the ability of a substance to change into another substance with new and different properties

Examples:Flammability – ability to burn
Nonflammable – will not burn

Physical changesaffect only the appearance
of a substance

Chemical changeis a process where a
substance changes intoanother substance
