Question

4.40 g of nitrogen gas at 20.0 ∘C and an initial pressure of 2.00 atm undergo an isobaric expansion until the volume has tripled.

Part A) How much heat energy is transferred to the gas to cause this expansion?

Part B) The gas pressure is then decreased at constant volume until the original temperature is reached. What is the gas pressure after the decrease?

Part C) What amount of heat energy is transferred from the gas as its pressure decreases?

A sample of nitrogen gas at a pressure of
0.942 atm and a temperature of 25.1
°C, occupies a volume of 18.5 liters. If
the gas is compressed at constant temperature to a
volume of 11.0 liters, the pressure of the gas
sample will be_________atm.

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...

21.3 moles of a diatomic ideal gas undergo three steps:
A to B is an isobaric (constant pressure P1
= 4.15x106 Pascal) expansion from volume
V1 = 0.0609 m3 to
V2 = 0.934 m3.
B to C is isochoric (constant volume)
C to A is isothermal (constant T).
During the isobaric expansion from A to B: find Q, the heat
transferred, in Joules. Give your answer in scientific
notation.
NOTE: A positive sign means heat has
been added; a negative...

A balloon is filled with oxygen (O2) at 20.0°C and 2.0
atm. The volume of the balloon after filling= 5.50 m3. The gas is
heated until its temperature= 80.0°C. During this process, the
balloon expands at constant pressure (2.0 atm). What is the heat
flow into the helium in J?

A container holds 1.50 g of oxygen at a pressure of 6.00 atm
a. How much heat is required to increase the temperature by 101

b. How much will the temperature increase if this amount of heat
energy is transferred to the gas at constant volume? (in C)

A container holds 1.5 g of argon at a pressure of 6.5 atm. How
much heat is required to increase the temperature by 100∘ C at
constant volume? How much will the temperature increase if this
amount of heat energy is transferred to the gas at constant
pressure?

A mole of a monatomic ideal gas is taken from an initial
pressure p and volume V to a final pressure 3p and volume 3V by two
different processes: (I) It expands isothermally until its volume
is tripled, and then its pressure is increased at constant volume
to the final pressure. (II) It is compressed isothermally until its
pressure is tripled, and then its volume is increased at constant
pressure to the final volume. Show the path of each process...
