Q.Interactive forces are .......... in ideal gas. a. nil b. small c. large d. same as that of real gases

The kinetic molecular theory of gases is the theoretical model that explains, from first principles about particle motion, why gases obey the empirically-observed gas laws. Its key assumptions are: gases consist of tiny discrete particles; these particles are, on average, so far apart that their own volume is negligible compared to the container's volume (explaining high compressibility); intermolecular attractive forces between gas particles are negligible at ordinary conditions (so gases expand to fill their container); particles move constantly, randomly, and in straight lines, colliding with each other and with the container walls; gas pressure arises directly from these particle-wall collisions; collisions are perfectly elastic (no net loss of kinetic energy); and, while individual parti …
