Question

One mole of an ideal gas is contained in a cylinder with a movable piston. The temperature is constant at 76°C. Weights are removed suddenly from the piston to give the following sequence of three pressures.

a. *P*_{1} = 5.10 atm (initial state)

b. *P*_{2} = 2.23 atm

c. *P*_{3} = 1.00 atm (final state)

What is the total work (in joules) in going from the initial to
the final state by way of the preceding two steps?

_________J (need this answer, and no it is not the same positive of
negative as the correct answer below)

What would be the total work if the process were carried out
reversibly?

-4728.235 J (correct)

Answer #1

A certain amount of chlorine gas was placed inside a cylinder
with a movable piston at one end. The initial volume was 3.00 L and
the initial pressure of chlorine was 1.64 atm . The piston was
pushed down to change the volume to 1.00 L. Calculate the final
pressure of the gas if the temperature and number of moles of
chlorine remain constant.
Enter a numerical answer only, in terms of
atm.

One gram-mole of ideal gas is contained in a piston-cylinder
assembly. Cp=(7/2)R, Cv=(5/2)R. The gas expands from 3 to 1 atm.
Heat of 1000J is transferred to the gas during the process.
External pressure maintains at 1 atm throughout. Initial
temperature of the gas is 300K. Find work and internal energy
change.

An ideal gas is enclosed in a cylinder with a movable piston on
top of it. The piston has a mass of 8,000 g and an area of 5.00
cm2 and is free to slide up and down, keeping the
pressure of the gas constant.
(a) How much work is done on the gas as the temperature of 0.155
mol of the gas is raised from 30.0°C to 330°C?
_______ J

A 19.0-L volume of an ideal gas in a cylinder with a piston is
at a pressure of 2.8 atm. Enough weight is suddenly removed from
the piston to lower the external pressure to 1.4 atm. The gas then
expands at constant temperature until its pressure is 1.4 atm.
Find the change in enthalpy, ?H, for this change in
state.
Express your answer using two significant figures.
Find the heat, q, associated with this change in
state.

One mole of ideal gas is confined in a piston-cylender device,
which is one foot in diameter. The piston can be assumed weightless
and frictionless. The internal and external pressures are both
initially 1 atm. An additional weight of 10 lbm is placed on top of
the pistion and the piston drops until the gas balances the force
pushing the piston downward. The temperature stays at a constant 80
degrees F.
What is the Final Pressure?

steam is contained in a piston and cylinder assemble at a
pressure of 5 bar and temperature of 700 degrees celcius. At this
initial condition, the cylinder is restrained by stops since the
pressure is applied on piston only supprts a pressure of 3 bar in
the cylinder. The initial volume of system is 1m^3 and cooling is
applied to the system until final volume is 0.1m^3. Determine work
and heat transfer.
