At very high pressures, real gases deviate from ideal behavior because the molecules occupy finite volume.Therefore, its actual volume is less than that predicted by the ideal gas equation. Opt:A is the answer
When there is high pressure, The distance between the adjacent gas molecules is relatively less, As a result, the real gas occupies a higher volume as compared to ideal gas subjected to high pressure due to due to absence of repulsion force in an ideal gas.
B right answers
No,option A. is right
Option b is correct
no it's less volume because ideal gas consider mass of molecule as a point but real gas takes some mass and therefore answer is (b)
