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.

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

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. P1 = 5.10 atm (initial state)
b. P2 = 2.23 atm
c. P3 = 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...

An ideal gas is brought through an isothermal compression
process. The 4.00 mol of gas goes from an initial volume of
259.4×10−6 m3 to a final volume of 110.6×10−6 m3 . If 8070 J is
released by the gas during this process, what are the temperature ?
and the final pressure ?? of the gas?
?= K
?f= Pa

An ideal monatomic gas is contained in a vessel of constant
volume 0.330 m3. The initial temperature and pressure of the gas
are 300 K and 5.00 atm, respectively. The goal of this problem is
to find the temperature and pressure of the gas after 24.0 kJ of
thermal energy is supplied to the gas.
(a) Use the ideal gas law and initial conditions to calculate
the number of moles of gas in the vessel. Your response differs
from the...

A cylinder with a piston contains 0.100 mol of nitrogen at
2.00×105 Pa and 320 K . The nitrogen may be treated as
an ideal gas. The gas is first compressed isobarically to half its
original volume. It then expands adiabatically back to its original
volume, and finally it is heated isochorically to its original
pressure.
A) Find the work done by the gas during the initial
compression
B) Find the heat added to the gas during the initial
compression...
