Topic: Thermodynamics
Wet clothes are hung on a clothesline outdoors in sub-zero weather. After a day, the clothes are brought into the house and observed to be dry. The process of drying is best explained as
- A. Vaporization
- B. Sublimation
- C. Melting
- D. Condensation
Answer: B. Sublimation
Explanation: In sub-zero temperatures, the water in the wet clothes first freezes into ice. Over time, this ice transitions directly from the solid phase into water vapor (gas) without passing through the liquid phase. This specific phase change is known as sublimation.
