Answer #1

question 1 the relationship between pressure and the volume of a gas (assume constant temperature)

answer 1) :- they are inversely proportional ( by Boyle's law )

question 2 What is the relationship between the temperature and the volume of a gas (assume constant pressure)

answer 2) ;- they are directly proportional ( Charles law )

question 3 What is the relationship between moles and volume of a gas? (assume all other variables are constant)

answer 3 :- they are equal ( Avogadro's law)

At a constant temperature, the number of moles (n) of an ideal
gas is a function of two variables ? = ?(?, ?) where P is the
pressure and V is the volume (Remember the ideal gas law ?? = ???,
where R is the universal gas constant). The number of moles
function is given as ? = ?(?, ?) = −? 2 + 4? − ? 2 + 6?. Find the
maximum and minimum values of the number of...

All pressure–volume–temperature relationships for gases can be
combined into a single relationship known as the combined gas
law. This expression can be used when looking at the effect of
changes in two of these variables on the third as long as the
amount of gas (number of moles) remains constant. To use the
combined gas law properly, you must always express the temperatures
in kelvins. The combined gas law can be represented as follows:
P1V1/T1=P2V2/T2

An ideal gas is heated under constant pressure (Pext
= 2 bar) from an initial volume of 1 liter and temperature
250C to a final temperature of 370C. what is
the final volume of the gas? how many moles of gas are
involved?

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...

According to Boyle's law, the pressure exerted by a constant
number of gas molecules in a container is inversely proportional to
the volume of the container. Therefore, increasing the volume of
the container will cause a decrease in its pressure.
True or False?

1. An unknown volume of gas has a pressure of 365 mm Hg and a
temperature of 52oC. If the pressure is raised to 1.2
atm, the temperature decreased to 47oC, and the final
volume measured to be 4.8×103 mL, what was the initial
volume of the gas in liters?
a. A gas that has a volume of 28 liters, a temperature of 45°C,
and an unknown pressure has its volume increased to 34 liters and
its temperature decreased to...

A container of gas at 2.8 atm pressure and 120∘C is compressed
at constant temperature until the volume is halved. It is then
further compressed at constant pressure until the volume is halved
again.
1.) What is the final pressure of the gas?(in atm)
2.)What is the final temperature of the gas?(in celsius)

A constant quantity of gas is at constant pressure and has a
volume of 10 L, and a temperature of 227 °C. To what temperature
does the gas need to be adjusted to reduce the volume by a factor
of 10?

One way to state Boyle's Law is "All other things
being equal, the pressure of a gas is inversely proportional to its
volume."
a) What is the meaning of the term "inversley proportional"?
b) What are the "other things" that must be equal?
