    D is the correct answer, Sourav.

    Sourav, the Z values depends for real gases...at low values of pressure, The Z value of most of the real gases are less than 1. But, as soon as the pressure is increased, it tends towards the value of 1. and if the pressure is increased further, it becomes greater than 1!

    Hydrogen and Helium gases have Z>1, always. But, rest all the real gas follows the same trend which I told you above. 😊

    does this means Z>1 z=1 Z<1 in the graph?

    eduncle-logo-app

    sourav at very high pressures the value of volume we calculated is less than the actual practical volume. Hence from the above two graphs, it is clear that generally real gases, under all conditions do not follow The Ideal Gas Behaviour or equation.

    Have you read deviation of real gas from ideal behaviour all causes

    and what about this?

    eduncle-logo-app

    I think its a

    eduncle-logo-app

    yes.. Bcoz z is greater than 1 na?

    eduncle-logo-app

    yes sourav

    eduncle-logo-app

    got sourav??

    eduncle-logo-app

    if any gas is not specified we will take z for all values and draw na?

    eduncle-logo-app

    These two ques which you asked....you can get similar type

    eduncle-logo-app

    for real gas and ideal gas

    eduncle-logo-app

    and for gas mentioned
