Answer:
PV=nRt
Therefore n(number of moles)=PV/RT
=>(0.49×3.80)/(0.08206×320)
Therefore Number of moles is = 0.071mols
Explanation: By using the Real gas equation..
PV=NRT .
We can solve for the number of moles of Ar by making N the subject..
Always make sure you pressure is In atm, your Volume is in Litres and temperature in degree Kelvin.
Also Recall the universal gas constant R used in this type of questions which is 0.08206.
Hence l, by making N the subject we get our answer as
<span>We can relate the average speed
of the gas molecules by its kinetic energy. The kinetic energy is the work done
by the object due to its motion. It is represented by the formula of the half
the velocity squared multiply by the mass of the object. The absolute zero
theory is the assumption that at 0 Kelvin or -273.15 degrees Celsius, the gas
molecules stop moving. It is because the temperature is severely cold enough to
allow movement of the gas molecules. The gas molecule that is closest to the
absolute zero is in cylinder B because it moves so slow and its movement is
almost near to the absolute zero theory.</span>
