Real gases approximate to ideal behaviour only at :-

Options in the attached image​

Answer 1

Answer:

Only at relatively low pressures (less than 1 atm) do real gases approximate ideal gas behavior (Figure 10.9. 1b). Figure 10.9. 1: Real Gases Do Not Obey the Ideal Gas Law, Especially at High Pressures
