o Temperature is a measure of the average amount of energy in a substance o Heat tells us how much total energy is in a substance Know the phases of matter, and the conversions between each. Know how particles act in each phase. o Solid o Liquid o Gas o Conversions: Solid/liquid Melting- solidliquid Freezing- liquidsolid Liquid/Gas Boiling- liquidgas Condensation- gasliquid Gas/Solid Sublimation- solidgas Deposition- gassolid Know the three gas laws that we discussed in class. Be able to use the formulas that are derived from the first two to solve problems. o Boyles- pressure and volume inversely related: P 1 V 1 =P 2 V 2

o Charles- temperature and volume directly related: V 1 T 1 = V 2 T 2 Know the equation for the Ideal Gas Law and understand how changing one variable in it will affect the other variables. o PV=nRT o P=pressure o V=volume o n= number of molecules o R=gas constant o T= temperature Know the difference between a physical property/change and a chemical property/change and be able to identify whether something is a physical or chemical change. Know the law of mass conservation and how it relates to chemical reactions.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
