Question

An ideal gas is compressed isothermally in a closed and frictionless piston/cylinder apparatus to 2.5 times its initial pressure, consuming in the process 2.2 kJ mol−1 of work. Calculate the temperature of the gas inside the cylinder.

Answer #1

A cylinder contains an ideal gas at the temperature of 300 K and
is closed by a movable piston. The gas, which is initially at a
pressure of 3 atm occupying a volume of 30 L, expands isothermally
to a volume of 80 L. The gas is then compressed isobarically,
returning to its initial volume of 30 L. Calculate the work done by
gas: a) in isothermal expansion; b) in isobaric compression, c) in
the whole process; and d) Calculate...

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?

A cylinder with a moveable piston holds 1.20 mol of argon at a
constant temperature of 295 K. As the gas is compressed
isothermally, its pressure increases from 101 kPa to 145 kPa.
(a) Find the final volume of the gas. (answer in:
m3)
(b) Find the work done by the gas. (answer in: kJ)
(c) Find the heat added to the gas. (.. kJ)

A cylinder sealed with a piston contains an ideal gas. Heat is
added to the gas while the piston remains locked in place until the
absolute temperature of the gas doubles.
1. The pressure of the gas a. doubles b. stays the same c. drops
in half
2. The work done by the surroundings on the gas is a. positive
b. negative c. zero
3. The thermal energy of the gas a. doubles b. stays the same c.
drops in...

A cylinder contains 1.5 moles of ideal gas, initially at a
temperature of 113 ∘C. The cylinder is provided with a frictionless
piston, which maintains a constant pressure of 6.4×105Pa on the
gas. The gas is cooled until its temperature has decreased to 27∘C.
For the gas CV = 11.65 J/mol⋅K, and the ideal gas
constant R = 8.314 J/mol⋅K.
1.Find the work done by the gas during this process.
2.What is the change in the internal (thermal) energy of...

A cylinder of monatomic ideal gas is sealed in a cylinder by a
piston. Initially, the gas occupies a volume of 3.00 L and the
pressure is initially 105 kPa. The cylinder is placed in an oven
that maintains the temperature at a constant value. 65.0 J of work
is then done on the piston, compressing the gas (in other words,
the gas does −65.0 J of work). The work is done very slowly so that
the gas maintains a...

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

Three kilograms (3.0 kg) of saturated steam at 162oC is held in
a closed piston-cylinder apparatus with a weighted piston that
exerts a constant force on the steam. The piston-cylinder apparatus
loses energy to the surroundings such that at a certain point 50%
of the steam has condensed to a saturated liquid inside the
cylinder (NOTE: the vapor and liquid are still saturated at the new
condition).
a. For the process described above, determine the heat exchange
with the surroundings....

One mole of an ideal gas
CP=7R2 in a closed
piston/cylinder arrangement is compressed from
Ti=200 K , Pi=0.5
MPa to Pf=5 MPa by following
paths:.
ADIABATIC path
ISOTHERMAL path
Calculate ΔU, ΔH, Q and WEC for both paths.
NOTE: Keep the answers in terms of ‘R’.

A fire breaks out and increases the Kelvin temperature of a
cylinder of compressed gas by a factor of 8. What is the final
pressure of the gas relative to its initial pressure?
_______ *p1
A quantity of gas in a piston cylinder has a volume of 0.413 m3
and a pressure of 200 Pa. The piston compresses the gas to 0.275 m3
in an isothermal (constant-temperature) process. What is the final
pressure of the gas? _______pa
