Boyle’s Law P1V1 = P2V2
Charles’s Law V1 / T1 = V2 / T2
Gay-Lussac's Law P1 / T1 = P2 / T2
Avogadro's Law V1 / n1 = V2 / n2
The Combined Gas Law P1V1 / T1 = P2V2 / T2
The Ideal Gas law PV = nRT
Dalton's Law of Partial Pressures Ptotal = Pa + Pb + Pc + …
Density of a Gas D=m/V
Graham’s Law r1/r2= sqrt (M2/M1)
Partial Pressure Pa= (P total)( mole fraction)
The average kinetic Energy of a Single Gas molecule KE=(½)mv^2
Molecular weight M=mRT/PV
Speed of molecules V rms=sqrt(3RT/M)
All of these formulas and laws basically make up the study of ideal gases. When we uses these formulas with the right variables. It allows scientists to find out the characteristics of different gases. However, sometimes it's difficult to find out which formulas and variables are provided in the question. In our class discussions over the past couple weeks, we basically went over lots of "dingle" worksheets. Everything was very straight-forward, however, it's super important to think about the concepts and how to apply the formulas into real world applications.
I felt very strong in understanding the concepts behind the gas laws. I am very confident about the upcoming test, mechanical calculations, and logics of ideal gases. If I am given all the needed variables. I am still confused on multiple step problems. On the taskchain and chemistry worksheets, I do not know what to do because there is no clear path (By clear path I mean it is not as straightforward like finding V2 if T1, T2, and V1 is given). I think to fix this, I should just do more problems to get more experience. Sometimes I still have couple mistakes when I am solving problems. I get lost very easily when the question gives out multiple variables in just one or two sentences. It distracts me from spotting out what variables are given to me and to determine which formulas should be use.
Although I get very confused sometimes in class. The moodle quizzes and lectures available for us online really helped me greatly. It gives me an understanding through just examining the components and step-by-step solving method. All I have left to do is basically just review and practice the worksheets and taskchains once again online to help me refreshing my memory. Practice! Practice! Practice! Hopefully I will do well on the test, or at least better than the last test that I took.
