Question

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 is the final temperature of the gas? (b) This process is best described as (circle one option):

Isothermal Isovolumetric Isobaric Adiabatic None of these

Answer #1

An insulated cylinder is fitted with an airtight piston that is
free to slide up and down and is connected to a rod. 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 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 quantity of gas in a piston cylinder is at room temperature
(20°C) and is heated in an isobaric(constant pressure)process. What
will be the temperature of the gas in degrees Celsius when it has
expanded to a volume of 0.600m3?

A gas is enclosed in a cylinder fitted with a light frictionless
piston and maintained at atmospheric pressure. When 254 kcal of
heat is added to the gas, the volume is observed to increase slowly
from 12.0 m3 to 16.2 m3 .
A. Calculate the work done by the gas
B. Calculate the change in internal energy of the gas.

A cylinder if fitted with a floating piston oriented
horizontally (the air is the system and by having a floating piston
it maintains constant pressure). It contains 24.5 L of air at 25.0C
and 1 bar pressure. The system is then heated to 250.0C. Air can be
considered a diatomic gas and therefore would have a Cv = 5R/2,
where R is the ideal gas constant. Also for gases Cp = Cv +R. How
much work was done (in J)...

An insulated cylinder is initially divided into halves by a
frictionless, thermally conducting piston. On one side of the
piston is 1 m3 of a gas at 300 K, 2 bar. On the other
side is 1 m3 of the same gas at 300 K, 1 bar.The piston
is released and equilibrium is attained, with the piston
experiencing no change of state. Employing the ideal gas model for
the gas, determine
(b) the final pressure, in bar.
(c) the amount...

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

A quantity of air is contained in a cylinder provided
with a movable piston. Initially the
pressure of the air is 4 × 107 N/m2
, the volume is 1.5 m3
and the temperature is 400 K.
Assume air is an ideal gas. (a) What are the final volume and
temperature of the air if it is
allowed to expand isothermally from initial conditions until the
pressure is 3 × 107 N/m2
and
then is cooled at constant volume until...

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...

A 19.0-L volume of an ideal gas in a cylinder with a piston is
at a pressure of 2.8 atm. Enough weight is suddenly removed from
the piston to lower the external pressure to 1.4 atm. The gas then
expands at constant temperature until its pressure is 1.4 atm.
