Answer #1

A) Carnot cycle is a full cycle of four steps

Step 1 : Isothermal expansion (P1, V1, T1) to (P2, V2, T1)

Step 2 : Adiabatic expansion (P2, V2, T1) to (P3, V3, T2)

Step 3 : Isothermal compression (P3, V3, T2) to (P4, V4, T2)

Step 4 : Adiabatic compression (P4, V4, T2) to (P1, V1, T1)

C) Table

Step 1 : Isothermal expansion (P1, V1, T1) to (P2, V2, T1)

dH = 0

dU = 0

w = -nRT1ln(V2/V1)

q = -w

Step 2 : Adiabatic expansion (P2, V2, T1) to (P3, V3, T2)

q = 0

w = Cv(T2 - T1)

dU = w

dH = Cp(T2 - T1)

Step 3 : Isothermal compression (P3, V3, T2) to (P4, V4, T2)

dH = 0

dU = 0

w = -nRT2ln(V4/V3)

q = -w

Step 4 : Adiabatic compression (P4, V4, T2) to (P1, V1, T1)

q = 0

w = Cv(T1 - T2)

dU = w

dH = Cp(T1 - T2)

Total,

Sum of all w's, q's, dU's and dH's

Consider n moles of an ideal monatomic gas being taken once
through the Carnot cycle of a thermal engine (motor), consisting of
two isothermal processes 1-2, 3-4 at temperatures T1 = 400K and T2
= 300K and two adiabatic processes 2-3 and 4-1. Suppose that all
processes are reversible.
a) Sketch the graph of the cycle in P-V diagram.
b) Calculate the heats of the processes 1-2, 3-4.
c) Prove that the efficiency of the engine depends only on the...

-Main features and applications.

Construct a Carnot PV-cycle for an ideal gas with high
temperature Thigh and low temperature Tlow. Remember that the top
and bottom legs are isotherms (constant temperature), so PV=NkT for
the start and endpoints of those legs. The side legs must satisfy
the condition that Delta(Q)=0. For your cycle, estimate 1) the work
done for each step (it will be helpful to have a piece of graph
paper), 2) the change in internal (heat) energy, 3) the total sum
of...

a. One mole of an ideal monoatomic gas (closed system, Cv,m)
initially at 1 atm and 273.15 K experiences a reversible process in
which the volume is doubled. the nature of the process is
unspecified, but the following quantities are known, deltaH=2000.0J
and q=1600.0J. Calculate the initial volume, the final temperature,
the final pressure, deltaU, and w for the process.
b. Suppose the above gas was taken from the same initial state
to the same final state as in the...

Chapter 16 Part 2: Question 16.3
An ideal Carnot engine takes 2000 J of heat from a reservoir at
500 K, does some work, and discards some heat to a reservoir at 350
K. Let’s see what happens if the Carnot engine described is run
backward as a refrigerator.What is its performance coefficient?
SOLUTION
SET UP AND SOLVE We know that a refrigerator
will act like an engine but with the signs for QH,
QC, and Wreversed because the cycle...

14.3 10.0 L of an ideal diatomic gas at 2.00 atm and 275K are
contained in a cylinder with a piston. The gas first expands
isobarically to 20.0 L (step 1). It then cools at constant volume
back to 275 K (step 2), and finally contracts isothermally back to
10.0 L (step 3). a) Show the series of processes on a pV diagram.
b) Calculate the temperature, pressure, and volume of the system at
