Question

Define an ideal gas and explain under which conditions you may reasonably approximate a real gas as an ideal gas. Also mention conditions under which it would be inappropriate to approximate a real gas as an ideal gas. (you may need to use a search engineto help you out here)

Answer 1

High temperature and low pressure

Step-by-step explanation:

According to the kinetic molecular theory, gases are composed of small particles called molecules which are in constant motion.

At high temperature and low pressure, gas molecules possess high kinetic energy and move at high velocities hence intermolecular interaction is almost none existent and real gases approach the behavior of ideal gases.
