Question

A gas is confined to a cylindrical volume with a movable piston on one end. Initially, the volume of the container is 0.200 m3, and the gas is at 295 K. The gas is heated, but the piston is moved such that the temperature of the gas remains constant. (a) If there are 2.30 mol of gas in the container, write an equation for the pressure of the gas as a function of the volume of the container. (Assume SI units. Do not include units in your answer. Use the following as necessary: V.)

P =_______ Pa

Answer #1

A quantity of air is contained in a cylinder provided
with a movable piston. Initially the
pressure of the air is 4 × 107 N/m2
, the volume is 1.5 m3
and the temperature is 400 K.
Assume air is an ideal gas. (a) What are the final volume and
temperature of the air if it is
allowed to expand isothermally from initial conditions until the
pressure is 3 × 107 N/m2
and
then is cooled at constant volume until...

A closed, cylindrical piston contains an ideal gas initially at
a volume of 1.00L, temperature of 25.0ºC and internal pressure of
1.00 bar. The gas is compressed by applying an external pressure of
1.5bar to a volume of 0.200L.
a. (20 pts) What is the work done in compressing the gas?
b. (15 pts) If the above piston had diathermal walls and the
process occurred isothermally, how much heat would be
exchanged?

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?

A gas is confined to a container with a massless piston at the
top. (Figure 2) A massless wire is attached to the
piston. When an external pressure of 2.03 bar is applied to the
wire, the gas compresses from 6.40 to 3.20 L . When the external
pressure is increased to 2.53 bar, the gas further compresses from
3.20 to 2.56 L .
In a separate experiment with the same initial conditions, a
pressure of 2.53 bar was applied to...

One mole of nitrogen gas confined within a cylinder by a
piston is heated from 0°C to
852°C at 1.00 atm.
(a) Calculate the work of expansion of the gas in
joules (1 J = 9.87 × 10−3 L·atm).
Assume all the energy is used to do work. (Enter your
answer in scientific notation.)
(b) What would be the temperature change if the gas were
heated with the same amount of energy in a container of fixed
volume? (Assume the...

A sealed container containing 3.8 mol of gas is squeezed,
changing its volume from 2.5×10−2 m3 to 1.5×10−2 m3. During this
process, the temperature decreases by 9.0 K while the pressure
increases by 800 Pa.
What was the original pressure of the gas in the container?
Express your answer using two significant figures.
What was the original temperature of the gas in the
container?

Think of the piston-cylinder system. Initially, it is filled
with pressure of 8 atmosphere, water of 0.1 m3 and steam of 0.9 m3.
The piston moved freely and heat was transferred to expand,
resulting in a final temperature of 350oC.

Steam is confined in a piston cylinder arrangement with an
initial volume of 0.625 cubic meters, an initial temperature of 150
degrees C, and an initial pressure of 16 pounds per square inch.
Then the piston is slowly moved so that the steam's volume is
decreased by 0.075 cubic meters in an isothermal process.
Calculate:
a. the final pressure
b. the work done by the steam
c. the change in the steam's internal energy
d. the change in entropy of...
