Question

21.3 moles of a diatomic ideal gas undergo three steps:

- A to B is an isobaric (constant pressure
*P*_{1}= 4.15x10^{6}Pascal) expansion from volume*V*_{1}= 0.0609 m^{3}to*V*_{2}= 0.934 m^{3}. - B to C is isochoric (constant volume)
- C to A is isothermal (constant
*T*).

During the isobaric expansion from A to B: find Q, the heat transferred, in Joules. Give your answer in scientific notation.

** NOTE**: A positive sign means heat has
been added; a negative sign means heat has been lost.

Answer #1

- Given-- number of moles
**(n) =21.3 mol** - diatomic gas, this means that
**degree of freedom (f) = 5.**(nothing is mentioned about bond, so we will take rigid bond) - heat is given to the system. Therefore,
**dQ**is**positive**. - Kindly give your feedback.
- Thank you.
- All the best.

See diagram 4.

A flask contains 99 moles of a monatomic ideal gas at pressure
6.79 atm and volume 29.3 liters (point A on the graph. Now, the gas
undergoes a cycle of three steps:
- First there is an isothermal expansion to pressure 3.71 atm
(point B on the graph).
- Next, there is an isochoric process in which the pressure is
raised to P1 (point C on the graph).
- Finally, there is an isobaric compression back to the original
state...

28 moles of an ideal gas with a molar specific heat at constant
volume of cv=3.2R is initially in state "A" at pressure 73390 Pa
and volume 1.0 m3.
The gas then expands isobarically to state "B" which has volume

3.0 moles of an ideal gas are subjected to the following
processes. First the volume is tripled in an isobaric process. Then
it undergoes an isothermal process to a pressure of 9.0 kPa. The
volume is then cut in half in another isobaric process after being
tripled. Finally, it returns to the original state in an isochoric
process. (a) Draw a PV diagram of the cycle. Label each state
(vertex) with a letter (A, B, …) and each transition with...

A container is filled with an ideal diatomic gas to a pressure
