An ideal monatomic gas is contained within a cylinder by a
moveable piston. The gas is in thermal contact with a heat bath
initially at 310 K. What is the change in molar
entropy if the gas is heated to 600 K if:
A. The piston is blocked
B. The piston is allowed to move freely against atmospheric
pressure

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...

Frictionless piston-cylinder system.
Initially contains 167 L of saturated liquid
Refrigerant-134a.
The piston can move freely in such that it maintains pressure at
877 kPa, an Isobaric process.
The Refrigerant-134a is heated until its temperature rises to 70
℃
Determine:
The work was done during the process in (kJ) units?

An insulated cylinder is fitted with an airtight piston that is
free to slide up and down and is connected to a rod, as shown in
the figure. Contained within the cylinder is an ideal gas initially
at a pressure of 120 kPa and temperature of 293 K. Suddenly the
piston is forced downward creating an additional 200 kPa of
pressure on the gas and as a result the cylinder volume decreases
to one-half of its original volume. (a) What...
