What is the difference between ideal gas equation and combined gas equation? Thank you
2 Answers
The ideal gas law is:
#(PV)/T = nR#
The combined gas law is:
#(PV)/T = "const"# where the pressure, temperature, volume, mols, and universal gas constant are given by
#P# ,#T# ,#V# ,#n# , and#R# , respectively.
The only difference is that the mols of gas are constant (this tends to be the case in a closed nonrigid container, where
In a more general scenario where
In fact, in most cases, the ideal gas law is more appropriate BECAUSE it is more general, and relevant conditions with constant variables can be derived.
Explanation:
Clearly, the Ideal Gas Law includes the amount of gaseous particles, represented by the molar quantity, whereas the combined gas equation requires a constant molar quantity. And thus the Ideal Gas Law includes Avogadro's experimental gas law,
