PLEASE ONLY DO D,E, F and G
A sample of 3 mol of Argon is put through the following cycle :
a. Express the kind of process for each step (1→2, 2→3, ...)
b. Predict if q, w, and ΔU will be positive, negative, or null for each step. Explain.
c. Find P, V, and T for each state.
d. Find the number of degrees of freedom (f), Cvm, Cpm, and γ for Argon.
e. For each step, find w, q, ΔU, and ΔH.
f. Add all q together, all w together, all ΔU together, and all ΔH together. What were you expecting?
g. If no information was given to you for State4, how would you find V4, P4, and T4?
No calculations needed, just explain.
