Mist is often seen around ice cubes. Which of the following is a proba...
Explanation:
Water vapor condenses when it hits the ice surface
- When water vapor in the air comes into contact with the cold surface of the ice cubes, it loses heat and energy.
- This causes the water vapor molecules to slow down and come together, forming tiny liquid water droplets.
- These liquid droplets are what we see as mist or fog around the ice cubes.
Reasons why water vapor condenses on the ice surface:
- The temperature of the ice cubes is lower than the dew point temperature of the surrounding air.
- The dew point temperature is the temperature at which the air becomes saturated and cannot hold any more water vapor.
- When the air comes into contact with the cold surface of the ice cubes, its temperature drops below the dew point temperature, causing the water vapor to condense.
Other possible reasons:
- Water molecules in the ice vaporize: This is not the probable reason because ice cubes do not vaporize water molecules. Instead, they absorb heat from their surroundings.
- The ice cools the air around it and thus producing a visible convection current: While the ice cubes do cool the air around them, this does not directly produce mist. Mist forms when water vapor condenses, not due to convection currents.
- The air molecule gets cold and becomes denser around ice cubes: While the air around the ice cubes does get colder, this does not directly result in the formation of mist. Mist forms when water vapor condenses, not due to changes in air density.

Understanding the Formation of Mist Around Ice Cubes
Mist often forms around ice cubes due to a process involving water vapor in the air. Let's explore the reason behind this phenomenon in detail.
Water Vapor and Condensation
- When ice cubes are placed in a warmer environment, they cool the surrounding air.
- This drop in temperature affects the air's ability to hold moisture.
Role of Temperature
- Warmer air can hold more water vapor compared to cooler air.
- As the temperature around the ice cubes decreases, the air becomes saturated with moisture, leading to condensation.
Condensation Process
- When warm, moist air comes into contact with the cold surface of the ice cubes, the water vapor condenses into tiny water droplets.
- These droplets cluster together, forming visible mist around the ice cubes.
Summary of Key Points
- The air around the ice cube cools down significantly.
- Water vapor in the warmer air cools and condenses into liquid water.
- This creates the mist that we often see surrounding ice cubes.
In conclusion, the presence of mist around ice cubes is primarily due to the condensation of water vapor in the air when it contacts the cold surface of the ice. This process highlights the interaction between temperature and humidity, demonstrating the fascinating principles of physics and chemistry in our everyday lives.
