Question

Inelastic collisions occur in:
I. Real gases
II. Ideal gases
III. Fusion reactions

• A. I and II
• B. II and III
• C. I and III
• D. I only
• E. II only

Answer 1

Answer: (C)

I and III

Inelastic collisions are those where maximum amount of kinetic energy if a system is lost.

In ideal gas, no such loss of energy from the system is there hence a perfectly elastic collision takes place.

In real gases and fusion reaction inelastic collisions takes place.
