Select the correct statement(s) :

Options

A. At Boyle's temperature a real gas behaves like an ideal gas at low pressure
B. Above critical conditions, a real gas behave like an ideal gas
C. For hydrogen gas 'b' domainates over 'a' at all temperatures
D. AT high pressure van der Waals' constant 'b' domainates over 'a'

Answer

a,b,d

Explanation

(a,b,d) For `H_(2)"gas IMAF"~~0`
`Zgt1 " " Z=1+(Pb)/(RT)`
at low pressure `Zlt1" "Z=1-(a)/(RTV_(m))`
Real gas behave like an ideal gas at low pressure and high temperature.
