Question

A sample of ideal gas at room temperature occupies a volume of
17.0 L at a pressure of 772 torr . If the pressure changes to 3860
torr , with no change in the temperature or moles of gas, what is
the new volume, *V*2?

If the volume of the original sample in Part A (*P*1 =
772 torr , *V*1 = 17.0 L ) changes to 50.0 L , without a
change in the temperature or moles of gas molecules, what is the
new pressure, *P*2?

Answer #1

Part A
A sample of ideal gas at room temperature occupies a volume of
27.0 L at a pressure of 202 torr . If the pressure changes to 1010
torr , with no change in the temperature or moles of gas, what is
the new volume, V2?
Express your answer with the appropriate units.
Part B
If the volume of the original sample in Part A (P1 =
202 torr , V1 = 27.0 L ) changes to 60.0 L...

A sample of ideal gas at room temperature occupies a volume of
36.0 L at a pressure of 692 torr . If the pressure changes to 3460
torr , with no change in the temperature or moles of gas, what is
the new volume, V2?

In the initial state, an ideal gas has pressure p1, volume V1
and temperature T1. Now the gas changes its state by effecting a
state change so that it reaches the pressure p2, the volume V2 and
the temperature T2 in the new state. The pressure doubles during
this state change, which is an isochore process.
a) Find the work W performed during the isochore process.
b) The heat Q is exchanged between the gas and the surroundings
during the...

Part A A sample of ideal gas is in a sealed container. The
pressure of the gas is 725 torr , and the temperature is 18 ∘C . If
the temperature changes to 75 ∘C with no change in volume or amount
of gas, what is the new pressure, P2, of the gas inside the
container? Express your answer with the appropriate units.
Part B Using the same sample of gas (P1 = 725 torr , T1 = 18 ∘C...

1. A sample of krypton gas occupies a volume of
9.48 L at 61.0°C and
407 torr. If the volume of the gas sample is
increased to 12.2 L, while its
temperature is decreased to
5.0°C, the resulting gas pressure will be what
torr?
2. A sample of carbon dioxide gas at a pressure
of 0.972 atm and a temperature of 225
°C, occupies a volume of 520 mL. If the
gas is heated at constant pressure until its
volume...

suppose your room volume is 41m^3. One mole of an ideal gas at STP
occupies a volume of 22.4 L
a) estimate the number of moles of air in your room
b) how many molecules is that?
c) there are N^N ways to distribute N things onto N sites. As
a rough approximation, assume there are as many states for air
molecules as there are air molecules in your room. Compute the
entropy of the air in your room.

A sample of gas in a balloon has an initial temperature of 33 ∘C
and a volume of 1650 L . If the temperature changes to 81 ∘C , and
there is no change of pressure or amount of gas, what is the new
volume, V2, of the gas?
What Celsius temperature, T2 , is required to change
the volume of the gas sample in Part A (T1 = 33 ∘C ,
V1 = 1650 L ) to a volume...

A. A sample of gas in a balloon has an initial temperature of 38
