1.	Which of the following statements is/are correct with respect to behaviour of real gas.
Answer» For every vander Waal gas at CRITICAL condition, attractive force will be dominant. The LIQUID and gaseous STATE can be distinguished only if the temperature is below the gas's critical temperature, At very HIGH pressures, real gases occupy greater VOLUME as compared to ideal gas having samo moles at same temperature and exerting same pressure. For a real gas the 'y' intercept of `(PV_m)/(T)` vs curve where 'P' represents pressure (in atm), `V_m` represents molar volume and ‘T’ represents temperature in kelvin is equal to 0.0821 atm-litre/mol Kelvin. Solution :At critical state `Z < 1 implies` attractions dominate only below `T_c`, gas can be liquified at higher P, `Z > 1 implies V_r > V_i`.
