Solution

Solution Steps

Step 1: Understanding Condensation on Surfaces

Condensation occurs when water vapor in the air comes into contact with a surface that is cooler than the surrounding air. The water vapor loses energy and changes from a gas to a liquid state, forming droplets on the surface.

Step 2: Identifying the Property of the Surface

The key property of the surface that causes water to condense on it is its temperature. Specifically, the surface must be cooler than the surrounding air, allowing it to lower the temperature of the air immediately adjacent to it.

Step 3: Determining the Required Temperature for Condensation

The specific temperature at which condensation occurs is known as the "dew point." The dew point is the temperature at which air becomes saturated with moisture and water vapor begins to condense into liquid water. For condensation to occur on a surface, the surface temperature must be at or below the dew point of the surrounding air.

Final Answer

The property of the surface that would cause water to condense on it is its temperature being cooler than the surrounding air.
The surface needs to equal the "dew point" temperature for condensation to occur.

\(\boxed{\text{2. Cooler surface temperature; 3. Dew point temperature}}\)
