Part A) A sample of a gas at 25°C and 1.0 atm
pressure has a volume of 2.5 L. The container is allowed to expand
until the pressure is 0.85 atm and the temperature is 15°C. The
final volume of the gas is __________ L.
Part B) A reaction is carried out that produces
hydrogen gas. The gas is collected in an inverted beaker over water
at 25 oC. The vapor pressure of water at 25
oC is 23.78 mmHg....
2.50 mole of perfect gas at 0°C is expanded from an initial
pressure of 5.00 atm to a final pressure of 1.00 atm against a
constant external pressure of 1.00 atm. (a) isothermally and (b)
adiabatically. (1) Calculate the values of q, w, DU, DH, DS, DSsur
and DStot for (a) and (b) (2) Draw p -V diagram to represent these
two different paths.
The pressure on a sample of an ideal gas is increased from 715 mmHg to 3.55 atm at constant temperature. If the initial volume of the as is 472 mL. what is the final volume of the gas?
A 4.00 L sample of gas is cooled from 71 CC to a temperature at which its volume is 2.60 L. What is this new temperature? Assume no change in pressure of the gas.

An ideal monatomic gas at an initial temperature of 500 K is
expanded from 5.0 atm to a final pressure of 1.0 atm. Calculate
w, q, DU, and (where applicable)
DH and DT when the expansion is performed (a)
reversibly and isothermally, and (b) reversibly and
adiabatically.
Help Please!!!
A monatomic ideal gas is at an initial pressure of 1.54 atm and
76.0 cm3. The gas undergoes an isochoric increase in pressure to
2.31 atm, then an isobaric expansion to 114 cm3. Pressure is
reduced isochorically to the original pressure before an isobaric
compression returns the gas to its initial values. For 1.95 moles
of the gas, complete the following:
a) Generate a sketch of the PV diagram, with values clearly
represented.
b) Find the heat absorbed and heat...
part a.) A sample of argon gas at a pressure of 1.05 atm and a
temperature of 21.0 °C, occupies a volume of 11.0 liters. If the
gas is allowed to expand at constant temperature to a volume of
15.6 liters, the pressure of the gas sample will be atm.
part b.) A sample of xenon gas at a pressure of
0.763 atm and a temperature of 29.9
°C, occupies a volume of 12.9 liters. If
the gas is allowed...
