Sr. # Questions Answers Choice
1 More ideal gas at room temperature is. CO2 NH3 SO2 N2
2 A real gas can be liquefied if. Temperature is more than critical temperature. Temperature is less than critical temperature Pressure is more than critical pressure and temperature is less than critical temperature Its pressure is less than critical pressure
3 An Ideal gas can not be liquefied because. Its critical temperature is always above 0 <sup>o</sup>C It molecules are relatively smaller in size Its solidify before becoming a liquid Force operative between its molecules are negligible
4 Which one of the following gases cannot be liquefied by Line's method. Water vapours NH3 Nitrogen H2
5 Gas molecules show more deviation from ideal behaviour at high pressure because. Velocity of molecules increases Velocity of molecules decreases Force of attraction between molecules increases Force of collision per unit area increases
