The value of van der Waal s constant a for gases CO2, N2, and SO2, are 3.59 ,1.39, 1.36, and 6.17 atm dm6 mol-2 respectively the gas which can be most easily liquefied is
If a graph is plotted between temperature on x-axis and volume on Y-axis for 1 mole of gas,then we get straight line which cuts the temperature axis at
