To solve the problem, we need to identify whether each scenario is an example of
evaporation,
condensation, or
dissolving. Let's analyze each situation step by step:
---
1. Salt being added to a soup
-
Process: Salt is being mixed into a liquid (soup).
-
Explanation: When salt is added to water (or soup), it dissolves, meaning the salt particles spread out and become uniformly distributed in the liquid.
-
Category:
Dissolving

2. Windows misting up on a cold day
-
Process: Water droplets form on the surface of the window.
-
Explanation: This occurs when warm, moist air inside the house comes into contact with the cold glass surface of the window. The moisture in the air cools down and changes from a gas (water vapor) to a liquid (water droplets). This is condensation.

3. Your clothes drying on a washing line
-
Process: Wet clothes lose their moisture over time.
-
Explanation: The water in the wet clothes changes from a liquid to a gas (water vapor) and escapes into the air. This is evaporation.
-
Category:
Evaporation

4. A lake drying up in hot weather
-
Process: The water level in the lake decreases.
-
Explanation: In hot weather, the water in the lake changes from a liquid to a gas (water vapor) and escapes into the atmosphere. This is evaporation.

5. Stirring sugar into a cup of tea
-
Process: Sugar is being mixed into a liquid (tea).
-
Explanation: When sugar is stirred into tea, it dissolves, meaning the sugar particles spread out and become uniformly distributed in the liquid.
-
Category:
Dissolving

6. Little drops of water on the outside of a glass of cold drink
-
Process: Water droplets form on the surface of the glass.
-
Explanation: This occurs when warm, moist air in the room comes into contact with the cold surface of the glass. The moisture in the air cools down and changes from a gas (water vapor) to a liquid (water droplets). This is condensation.
