you want to cool a storage cylinder containing 10 moles of compressed gas from 30oc to 20oc. for which kind of gas would this be easiest?
The answer to this question is A – Monoatomic Gas Explanation- A monoatomic gas has only one atom and its degree of freedom is three (3). It means it can only have translation motion in any of the three axes. Diatomic gas has 5 degrees of freedom
you want to cool a storage cylinder containing 10 moles of compressed gas from 30oc to 20oc. for which kind of gas would this be easiest?
Volume of oxygen, 30 litres
Gauge pressure, 15 atm
Temperature,
Universal gas constant,
Let the initial number of moles of oxygen gas in the cylinder be n1 .
The gas equation is given as:
Universal gas constant,
Let the initial number of moles of oxygen gas in the cylinder be n1 .
The gas equation is given as:
But
Where,
Initial mass of oxygen
M = Molecular mass of oxygen = 32 g
Where,
Initial mass of oxygen
M = Molecular mass of oxygen = 32 g
After some oxygen is withdrawn from the cylinder, the pressure and temperature reduces.
Volume, 30 litres
Volume, 30 litres
Gauge pressure, 11 atm
Temperature,
Let be the number of moles of oxygen left in the cylinder.
The gas equation is given as:
The gas equation is given as:
But
Where,
is the mass of oxygen remaining in the cylinder
The mass of oxygen taken out of the cylinder is given by the relation:
Initial mass of oxygen in the cylinder – Final mass of oxygen in the cylinder
Where,
is the mass of oxygen remaining in the cylinder
The mass of oxygen taken out of the cylinder is given by the relation:
Initial mass of oxygen in the cylinder – Final mass of oxygen in the cylinder
Therefore, 0.131 kg of oxygen is taken out of the cylinder.
