Assuming that gas being used is an ideal gas, the gas law equation PV=nRT can be used.
P=Pressure (atm)
V=Volume (Liters)
n=Moles
R=0.08206 (a gas constant)
T=Temperature (Kelvin)
In this problem we know that there is a 10L container with 3.84atm of pressure at 35 C. So P=3.84atm, V=10L, and R=0.08206.
To calculate T, you need to convert from Celsius (C) to Kelvin (K). Using the formula K=273+C, you should get T=308K.
Now you know all of the variables you can work the problem out.
Solve the equation for moles(n) by dividing each side by R and T:
(PV/RT)=n
Plug in your numbers and solve with a calculator:
n=(3.84)(10)/(0.08206)(308)
=(38.4)/(25.27448)
=1.5193190918
Leaving us a rounded answer of 1.52n in the container

Is water a solid liquid or a gas at 20 degrees?
Water's freezing point is 0 degrees Celsius, so anything below that is a solid. Water's boiling point is 100 degrees Celsius, so anything between 0 and 100 would be a liquid, and anything above 100 would be a gas.
Is 0 degrees on the celsius scale?
Yes, 0 degrees is present on the Celsius scale.
If a cold front is present is a high pressure system present?
No, but a low pressure is.
Why if a gas is present at 27 Celsius its volume becomes doubled when temperature increases to 327 Celsius under constant pressure?
pV = nRT we can firstly assume that n (number of moles) and R (gas constant) do not change and as pressure is also kept constant, the temperature must be proportional to the volume. Thus if temperature is increased from 27C (300K) to 327C (600K) and is doubled, the volume must also double.
What substance present in your body balances the atmospheric pressure actin on us?

What is the pressure of a container that has a vacuum inside of it?
Since there's no particles present, there's no pressure.
How is water present in liquid form even at tepratures less than 0 degree celsius?
Under higher pressure.
Does the pressure exerted by a gas depend on its molar mass?
It depends on the density of the gas which is mass/volume. And the density can change if the temperature or/and pressure change. The volume (V) of a gas is dependent on the formula: V=(nRT/P) - This is the ideal gas law Where P is the pressure of the vessel the gas is present in, T is the temperature it is kept, R is the gas constant. The last variable, "n"; is the amount of moles of the gas you have. The number of moles is dependent on the molecules or atoms of the substance that the gas is comprised of. Due to this the mass does affect the Volume of the gas. This is because the more molecules of the substance you have, the more moles will be present. Since there will be more moles there will be a greater mass. The opposite is true in the opposite. We can see from the formula that the relationship is directly proportional More Mass = More Volume So the answer is yes.
Is water a solid liquid or a gas at 20 degrees?
Water's freezing point is 0 degrees Celsius, so anything below that is a solid. Water's boiling point is 100 degrees Celsius, so anything between 0 and 100 would be a liquid, and anything above 100 would be a gas.
How a gas exerts pressure on the walls of its container?
The gaseous molecules are in continuous random motion and during their motion continuously strike the walls of container and exert the force on walls,the force per unit area is the pressure of the gas.
Is pressure of a gas an extensive property in a closed container of constant volume?
Yes. It depends on the amount of gas present (as well as the temperature of the gas.)
What determines the shape a volume of a gas inside a container?
The shape of the gas is determined by the shape of the container (assuming that there is enough gas to fill the container). The volume of the gas is determined by the volume of the container (again assuming that there is enough gas present to fill the container.). When a gas is introduced into any container, it will assume the size and shape of the container if the container is filled. The exception to this rule might be if the pressure of the gas introduced is great enough to influence the shape of the container (i.e. blowing up a balloon).
Is 0 degrees on the celsius scale?
Yes, 0 degrees is present on the Celsius scale.
If a cold front is present is a high pressure system present?
No, but a low pressure is.
What is the quantity of air in the atmosphere above your head?
The quantity of air in the atmosphere above our head is about 250 kilograms which is about the weight of two baby elephants. But we don't feel the enormous weight is balanced by the pressure exerted by the blood and other fluids present in our body
Why if a gas is present at 27 Celsius its volume becomes doubled when temperature increases to 327 Celsius under constant pressure?
pV = nRT we can firstly assume that n (number of moles) and R (gas constant) do not change and as pressure is also kept constant, the temperature must be proportional to the volume. Thus if temperature is increased from 27C (300K) to 327C (600K) and is doubled, the volume must also double.
What loads are present in pneumatic?
The wind pressure is the pressure of the gases.
