A flask contains 99 moles of a monatomic ideal gas at pressure
6.79 atm and volume 29.3 liters (point A on the graph. Now, the gas
undergoes a cycle of three steps:
- First there is an isothermal expansion to pressure 3.71 atm
(point B on the graph).
- Next, there is an isochoric process in which the pressure is
raised to P1 (point C on the graph).
- Finally, there is an isobaric compression back to the original
state...

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...

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...

Consider the following four-process cycle that is carried out on
a system of monatomic ideal gas, starting from state 1 in which the
pressure is 88.0 kPa and the volume is 3.00 liters.
Process A is an isothermal process that triples the
volume;
process B is a constant volume process that returns the system to a
pressure of 88.0 kPa;
process C is an isothermal process that returns the system to a
volume of 3.00 liters;
and process D is...

A cylinder containing 3.0 moles of a monatomic, ideal gas begins
at a pressure of
2.0 × 105 Pa, with a volume of 0.0365 m3. The
gas then goes through the following three processes, which comprise
a thermal cycle:
The gas is expanded isothermally, to twice its original
volume.
The gas is cooled isobarically, back to its original
volume.
The gas is heated isochorically, up to its original
pressure.
(a) Find the initial temperature of the gas, in
Kelvin.
(b)...

A flask contains 90.7 moles of a monatomic ideal gas at pressure
5.64 atm and volume 40.1 liters (point A on the graph. Now, the gas
undergoes a cycle of three steps:
- First there is an isothermal expansion to pressure 3.79 atm
(point B on the graph).
- Next, there is an isochoric process in which the pressure is
raised to P1 (point C on the graph).
- Finally, there is an isobaric compression back to the original
state...

A frictionless piston-cylinder device and a rigid tank contain
3.3 kg of neon gas at the same temperature, pressure and volume.
Now heat is transferred, and the temperature of both systems is
increased by 10 degrees C. The amount of extra heat that must be
supplied to neon gas in the cylinder that is maintained at constant
pressure is ...

2.)1.0 mol sample of an ideal monatomic gas originally at a
pressure of 1 atm undergoes a 3-step process as follows:
(i) It expands
adiabatically from T1 = 588 K to T2 = 389 K
(ii) It is compressed at
constant pressure until its temperature reaches T3 K
(iii) It then returns to its
original pressure and temperature by a constant volume process.
A). Plot these processes on a PV diagram
B). Determine the temperature T3
C)....

A balloon contains Helium (a monatomic ideal gas) at a pressure
of 101325Pa and temperature of 20.0◦C. Please note that the
pressure inside of a balloon must always equal the atmospheric
pressure outside of the balloon.
(a) If the volume of the balloon is 0.015m3, how many moles of
Helium are inside the balloon?
(b) What is the rms speed of the Helium in the balloon? (The
molar mass g
of Helium is 4.002602mol.)
(c) If the temperature of the...

A vertical cylinder contains N molecules of a monatomic ideal
gas and is closed off at the top by a piston of mass M and area A.
The acceleration due to gravity is g. The heat capacities of the
piston and cylinder are negligibly small, and any frictional forces
between the piston and the cylinder walls can be neglected. The
whole system is thermally insulated. Initially, the piston is
clamped in position so that the gas has a volume V0...
