Welcome to PHY 121 Blog Help. Here's how it works. For each homework question and lab report we will make a post, this will probably contain a few tips on what the problems are about and how to solve them. If you are stuck on something then instead of emailing us directly you should post a comment in reply to the relevant post. We will try to guide you through tough points and help you understand the problems and the concepts behind them.

my values are; 860 degress C which I made 1113.15, Pressure 3atm, initial vol=300 and final =100 which i made 3*10^-4 and 1 *10^-4 respectively. Delta v i got -2*10^-6. For N i didN=PV/KT and that was 3*(-2*10^-6)/(1.38^-23) * (1113.15) and I got -4.05*10^14 which is wrong. what did i mess up?
Hello everyone, I'm Lea Paige Matteo from Zurich Switzerland and want to use this medium to express gratitude to Mr Benjamin service for fulfilling his promise by granting me a loan, I was stuck in a financial situation and needed to refinance and pay my bills as well as start up a Business. I tried seeking for loans from various loan firms both private and corporate organizations but never succeeded and most banks declined my credit request. But as God would have it, I was introduced by a friend named Lisa Rice to this funding service and undergone the due process of obtaining a loan from the company, to my greatest surprise within 5 working days just like my friend Lisa, I was also granted a loan of $216,000.00 So my advice to everyone who desires a loan, "if you must contact any firm with reference to securing a loan online with low interest rate of 1.9% rate and better repayment plans/schedule, please contact this funding service. Besides, he doesn't know that I am doing this but due to the joy in me, I'm so happy and wish to let people know more about this great company who truly gives out loans, it is my prayer that GOD should bless them more as they put smiles on peoples faces. You can contact them via email on { 247officedept@gmail.com} or Text through Whatsapp +1-989 394 3740.

For the initial temp do we do Tfinial-Tinitial = W/(3/2*N * K)? cause mines not working
how do you solve for the number of moles? I've tried using the ideal gas equation, but it doesn't seem to work.
You supposed to use ideal gas equation to solve for number of moles. Do you use SI units? For what point on the graph you are applying an equation?
do we just use 3 atm for the pressure or convert it to something
Yes, in appropriate units
How Mr Benjamin Lee service granted me a loan!!!
