3 moles of an ideal gas with 2 atoms under 308 K temperature and
5 atm are expanded reversible to 1 atm end pressure. Calculate w,
q, ΔU, ΔH values in case of expansion of this expansion by
isothermal and adiabatic way.
If 6.00 moles of a monatomic ideal gas at a temperature of 260 K
are expanded isothermally from a volume of 1.07 L to a volume of
4.61 L .
Calculate the work done by the gas.
Calculate the heat flow into or out of the gas.
If the number of moles is doubled, by what factors do your
answers to parts A and B change?
a) Consider 1.3 moles of an ideal gas at an initial temperature
of 400 K and in a 1.2 m3 closed container. If the gas
goes through an isochoric process to twice the initial temperature,
what is the new pressure of the gas in Pa?
b) Consider 1.3 moles of an ideal gas at an initial temperature
of 400 K and in a 1.2 m3closed container. If the gas
goes through an isothermal process to 3.6 m3, what is

5 moles of ideal gas is initially at 300 K and 5 bar. It is
compressed to 10 bar at 300 K. This change is carried out by two
different reversible processes:
A: heating at constant volume followed by cooling at constant
pressure
B: cooling at constant pressure followed by heating at constant
volume
Depict these processes on a PT graph. (Hand drawn on engineering
sheet would suffice). Calculate ΔU,
ΔH, Q, and W requirements for each path.
Cv=20.78 J/mol.K...
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.

Three moles of an ideal monatomic gas expand at a constant
pressure of 2.40 atm ; the volume of the gas changes from
3.20×10-2 m3 to 4.50×10−2
m3 .
a. Calculate the initial temperature of the gas.
b. Calculate the final temperature of the gas.
c. Calculate the amount of work the gas does in expanding.
d. Calculate the amount of heat added to the gas.
e. Calculate the change in internal energy of the gas.
For 1 mol of an ideal gas, Pexternal = P = 1 atm. The
temperature is changed from 125ºC to 25.0ºC, and CV,m = 3/2R.
Calculate (all units are J) q= , w= , ∆U= , and ∆H= . Please enter
your answers with 2 decimals in E notation, such as 2.33E4
(=23345). If the answer is negative, please do not forget the
negative sign. If answer is zero, please just enter 0 without
decimal.
Consider a monoatomic ideal gas of N moles in a gas cylinder
eqilibrated at temperature T1 and pressure P1 by a mass placed on
the piston. Upon removal of the mass , the gas reaches a new
eqilibrium pressure P2 (<P1). Calculate the amount of work done
by the gas on the surroundings for the following processes.
