### Step-by-Step Solution: 1. **Understanding the Question**: The question asks why we can sip hot tea or milk faster from a saucer compared to a cup. We need to consider the properties of liquids and how they behave in different containers. 2. **Surface Area Consideration**: A saucer has a larger surface area compared to a cup. This is an important factor because the surface area of a liquid affects how quickly it can cool down. 3. **Evaporation Rate**: When a liquid is exposed to air, it can evaporate. The rate of evaporation increases with a larger surface area. Therefore, since a saucer has a larger surface area, the hot tea or milk in a saucer will evaporate more quickly than in a cup. ...
