A gas deviates from ideal behaviour at a high pressure because its molecules
Topic: JEE PYQ
Answer: C. Full step-by-step solution below.
- Ahave kinetic energy
- Bare bound by covalent bonds
- Cattract one another
- Dshow the Tyndall effect.
Correct answer: C
Solution
(c) : Some attractive forces exist between the molecules of real gases. When a molecule approaches the wall of the container it experiences an inward pull as a result of attractive forces exerted by the neighbouring molecules inside the vessel. Therefore the observed pressure is less than the ideal pressure and hence gas deviates from ideal behaviour at high pressure.More States of Matter PYQs
