Question

9. A 2mole sample of diatomic gas is placed in a sealed container. The initial volume of the container is 2m3 but then the lid is pushed down, causing 2500J of mechanical work to be done on the gas to compress it isobarically to 1.5m3. a) What is the pressure of the gas? (2pts) b) What is the thermal energy lost through heat by the gas? (4pts)

Answer #1

A container is filled with an ideal diatomic gas to a pressure
and volume of P1 and V1,
respectively. The gas is then warmed in a two-step process that
increases the pressure by a factor of five and the volume by a
factor of three. Determine the amount of energy transferred to the
gas by heat if the first step is carried out at constant volume and
the second step at constant pressure. (Use any variable or symbol
stated above...

An ideal gas in a sealed container has an initial
volume of 2.75 L. At constant pressure it is cooled to 21.00
Celsius where its final volume is 1.75 L. What was the initial
temperature?

3)Gas in a container is at a pressure of 1.1 atm and a volume of
5.0 m3. (a) What is the work done on the gas if it expands at
constant pressure to twice its initial volume? J (b) What is the
work done on the gas if it is compressed at constant pressure to
one-quarter of its initial volume? J

. A container has n = 3 moles of a monoatomic ideal gas at a
temperature of 330 K and an initial pressure of three times the
atmospheric pressure. The gas is taken through the following
thermodynamic cycle: 1.- The gas is expanded isobarically (constant
pressure) to Vf = 2.5∙Vi. 2.- The pressure of the gas is decreased
isochorically (constant volume) to half of the initial value. 3.-
The gas is compressed isobarically back to its initial volume. 4.-
The...

A 1.79 mol diatomic gas initially at 274 K undergoes this cycle:
It is (1) heated at constant volume to 707 K, (2) then allowed to
expand isothermally to its initial pressure, (3) then compressed at
constant pressure to its initial state. Assuming the gas molecules
neither rotate nor oscillate, find (a) the net energy transferred
as heat to the gas (excluding energy transferred as heat out of the
gas), (b) the net work done by the gas, and (c)...

A 3.44 mol diatomic gas initially at 346 K undergoes this cycle:
It is (1) heated at constant volume to 909 K, (2) then allowed to
expand isothermally to its initial pressure, (3) then compressed at
constant pressure to its initial state. Assuming the gas molecules
neither rotate nor oscillate, find (a) the net energy transferred
as heat to the gas (excluding energy transferred as heat out of the
gas), (b) the net work done by the gas, and (c)...
