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.

#4 A system containing 2.50 moles of an ideal gas for which =
20.79 JK-1mol-1 is taken through the
following cycles: (1) an isobaric expansion (P1 = 16.6

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

factor of three. Determine the amount of energy transferred to the
gas by heat if the first step is carried out at constant volume and
the second step at constant pressure. (Use any variable or symbol
stated above...

An engine based on 50 moles of diatomic gas tries to split the
difference between the Carnot and Otto cycles and invokes a
three-step design: 1) an adiabatic expansion from 70 K to 350K, 2)

We consider an isolated system made up of 2 moles of an ideal
gas which can pass reversibly from a state A (PA, VA, TA = 300 K)
to a state B (PB = 3PA, VB = VA / 3, TB) by a transformation which
comprises two stages: it is first isochoric (constant volume), then
isobaric (constant pressure).
