A sample of 1.00 mol perfect gas molecules with C = –7R is put through p, m 2 the following cycle: (a) constant-volume heating to twice its initial volume, (b) reversible, adiabatic expansion back to its initial temperature, (c) reversible isothermal compression back to 1.00 atm. Calculate q, w, ∆U, and ∆H for each step and overall.

Choose all that apply. when creating a graph, you should: determine the x- and y- variables label the scale on the x- and y- axes plot the data points draw a line of best fit to represent the data trend
