Under which conditions van der Waals real gas acts as an ideal gas?

Step-by-step solution

At high temperature and low pressure real gas acts as an ideal gas and obey p ~V =n RT relation. for real gases, (p- n^2 a ~V ^2 )( V -n b)= RT Van der Waals isotherms demonstrates the relationship between pressure, volume, and temperature based on the van der Waals model. The constants a and b have positive values and are specific to each gas. The higher the value of a, the greater the attraction between molecules and the more easily the gas will compress. The b term represents the excluded volume of the gas or th
