Question

The sound takes minimum time to travel from one place to another :

• A. at night
• B. during summer
• C. during winter
• D. all the time same

Answer 1

The correct option is C during winter

At low temperatures(during winter) molecules in the atmosphere r closely packed and at high temperatures(during summer) molecules r loosely packed.Molecules which r closely packed transfer energy faster than the molecules which r loosely packed. Hence sound( energy )travel faster in winter than in summer.
