In this experiment, it was assumed that hydrogen behaves as an ideal gas. Is this a valid assumption Explain. nRT

Answer 1

Ans: 1) Yes, Hydrogen can be assumed to be an ideal gas because of low intermolecular forces ('a' is very small) and low volume of gas( 'b' is very small).

This will reduce Vander waal's equation to

PV=nRT, by neglecting terms associated with 'a' and 'b’ .
