Question
Why is steam more efficient than air for sterilization?
Correct Answer
Option C is the correct answer.
Detailed Explanation
Steam is more efficient than hot air for sterilization due to its high latent heat of vaporization. When steam condenses on cooler surfaces, it releases a large amount of energy (latent heat) at a constant high temperature, providing more effective and rapid heat transfer compared to dry hot air.
Hint
Think about the energy released when water changes from a gas to a liquid.
