Number 13. Question at the back of the book. A real gas has a volume, so would the answer be "A" because the volume available for the gas particles is less than container? I get this confused. One could argue that the gas having volume means That the total volume is more than container which is why the ideal gas law subtracts it.

Definition Definition Law that is the combined form of Boyle's Law, Charles's Law, and Avogadro's Law. This law is obeyed by all ideal gas. Boyle's Law states that pressure is inversely proportional to volume. Charles's Law states that volume is in direct relation to temperature. Avogadro's Law shows that volume is in direct relation to the number of moles in the gas. The mathematical equation for the ideal gas law equation has been formulated by taking all the equations into account: PV=nRT Where P = pressure of the ideal gas V = volume of the ideal gas n = amount of ideal gas measured in moles R = universal gas constant and its value is 8.314 J.K-1mol-1 T = temperature
Expert Solution
Step 1
Ideal gases are those gases which follow ideal gas equation at every temperature and pressure conditions. Real gases are those gases which do not follow ideal gas equation at all temperature and pressure. These gases follow the ideal gas equation only at high pressure and low temperature.
