Two Questions

Hello, I would appreciate any input on these two questions. 1. I came across this question: “What is the final temperature of 1 mol of gas that performs 50J of work adiabatically? The initial temperature is 0 Celsius. (Gas const = 8.314J/(mol*K))?” They find the answer by doing PV=nRT, and get Tf = 6 Celsius. I’m wondering why they didn’t do -W = dU = n*cv*dT = 3/2 n*R*dT? 2. On one of the MCAT practice tests (AAMC MCAT Test 3R) in the Biological Sciences section #203 it asks: “A man... Read more
