Here is my issue with this problem. For part B, I believe I am
using the right method; for S2-S1 using table values I am getting
0.54336 kJ/K. The formula for total S is supposed to be
S total = (S2-S1) - Q/T. But for Q/T I am getting a little over the other value giving me a negative answer. It just is not seeming right. This when plugged in, doesn not give 0.056 kJ/K which is apparently correct. Someone help me figure out what is up here please.

Given: A vertical piston-cylinder device contains air, which is initially at 900 kPa and 250°C and occupies a volume of 0.005 m². The frictionless piston is anchored by a hard stop in the expansion direction, but moves freely in the compression direction. The piston weighs 200 kg and has an area of 0.005 m². Heat is removed...

Hello, I am having trouble with a problem in my C language class. I am trying to make a program with the following requirements: 1. Use #define to define MAX_SIZE1 as 20, and MAX_SIZE2 as 10 2. Use typedef to define the following struct type: struct { char name[MAX_SIZE1]; int scores[MAX_SIZE2]; } 3. The program accepts from the command line an integer n (<= 30) as the number of students in the class. You may assume that the...

Hello, I am looking for help and an explanation for part c of this problem. Assume that solutions of PhEt : PhH behave ideally. a) Calculate the entropy of mixing if 40 g of PhEt is mixed into 50 g of PhH. --> 5.57 J/K b) At room temperature (298K), what is delta G mix for mixing 40 g of PhEt and 50 f of PhH? --> -1.66 kJ c) Would you notice a temperature change associated with the process...

Question 6 0 out of 10 points A piston-cylinder assembly contains 1.2 kg of air at T1- 300 K and P1 200 kPa. The air is brought to a final temperature of T2 946 K at fixed volume (the piston does not move). Determine the total heat transfer Q (kJ) into the assembly during the process. Note: Use the ideal gas tables for your calculations. Ideal Gas Properties of Air 200 1.00424 199.97...
