Its question 4.2.1-2 on the attachment
This question refers to a process involving three moles of a diatomic gas (which behaves as an ideal gas, but as is typical near room temperature,with vibrational modes frozen out). The PV curve at right describes this process. Determine the energy transferred as work, the change in internal energy, and the energy transferred as heat in this process.
In the PV diagram they give P initial as 60 Pa x 105 and P final as 55 Pa x 105. Temp initial is 337K and Temp final is 353K. Vol initial is 1.4 m3 x 10-3 and Vol final is 1.6 m3 x 10-3.
I know that delta E = Q+W and here Q+W cant be 0 because the heat entering the system changed the temperature and caused work to be done on the gas I believe.
So I have been trying to figure this out for a while and I don't think I understand this topic very well. In my notes form lecture I have multiple equation about finding work and I'm not sure which one to use. To solve for the internal energy change do I use the equation n*Cv*deltaT or do I multiply the change in pressure by the change in temperature?

4.1.1-5) Is it possible for an ideal gas to undergo an isobaric process in which ?U = 0? If so, sketch a
PV diagram for such a process.
4.2.1-2) Using multiple models simultaneously: This FNT refers
to a process involving three moles of a diatomic gas (which
behaves as an ideal gas, but as is typical near room temperature,
with vibrational modes frozen out). The PV curve at right
describes this process.

4.2.1-1) Use your results from Activity 4.2.1 to determine a value of the heat of vaporization of one
mole of water at 30?C and standard atmospheric pressure.
T = 337K
T = 353K
Determine the energy transferred as work, the change in internal
energy, and the energy transferred as heat in this process.

One mole of an unknown ideal gas (monatomic? diatomic? could be any number of
atoms in each molecule) completes a cyclic process shown in the
PV diagram at right.
a) What is the magnitude of the work done on the gas over one
complete cycle (I to II to III to I)? (Hint: think of this cycle as
three separate pieces that are summed-over to get the
b) What is the net change in internal energy of the gas over one
complete cycle? Explain how you determined this.

P [Pa × 10 5]
c) During the portion of the process going directly between points
III and I, 3000J of heat was removed. Using this information
determine whether this gas is monatomic diatomic, or what,
and explain the steps you used to determine this.
4.2.1-4) Two different processes (A) I to IIa to III,
and (B) I to IIb to III can take a mole of an ideal monatomic gas
from an initial state I to a final state III.
a) How much work is done on/by the gas in each step of both
processes (A) and (B)?
b) How much energy is transferred as heat to/from the gas in
each step of both process (A) and (B)?
