MHT CET Chemistry Question (2026) — Solution
Options
- A. It shows deviation from Boyle's law and Charles' law.
- B. Its molecules are not perfectly elastic.
- C. It does not exist.
- D. Intermolecular attraction is present in it, hence a collision takes place with loss of kinetic energy.
Answer
C. It does not exist.
Step-by-step solution
An ideal gas is a hypothetical concept and does not exist in reality. Real gases behave as ideal gases only under conditions of low pressure and high temperature. According to the kinetic theory of gases, an ideal gas strictly obeys Boyle's law, Charles' law, and other gas laws under all conditions of temperature and pressure. The collisions between its molecules are perfectly elastic, and there are no intermolecular forces of attraction between its molecules. Thus, the statement that it does not exist is true. Answer: It does not exist.
