I'm sorry I cannot conform to the default format Physicsforums.com; it is because I do not even know the first step to solving these sorts of problems, I don't know which equations to use which is a major problem. Here are the types of questions I require understanding. - An ideal gas goes through three processes (A>B>C>[A]) (Triangular form) (PV Chart) How would I figure out The Q, W, and ΔU (internal energy) for A to B, B to C, C to A? - On another graph using variables but this time with numerical values for P and V on the axis, how would I find the work done by a monatomic ideal gas as it expands from point A to point C along the path shown in the figure? Also, how much heat would be absorbed BY the gas during this process? - Finding the net work, heat, and ΔU in another PV Graph with data on the axis-es? - Calculating temperature, work, and/or internal energy in another PV Graph? - Whether or not W, Q, or ΔU is positive(gained) or negative(released) in an ideal gas system as well as how those three (Q,W,..U) are related? - I really wish to work on the problems myself, so I have only asked what procedures I should take. Here is a list of equations I have scavenged. ΔU = Won + Q ΔU = (3/2)nRΔT Won = -PΔV P1V1 = P2V2 (P1V1)/T2 = (P2V2)/T2 PV = nRT Is there any important equation that I am missing?
