The temperature and the dew point in an open room are `20^(@)C and 10^(@)C`.if the room temperature drops to `15^(@)C`,what will be the new dew point?

Explanation

To solve the problem, we need to understand the relationship between temperature and dew point. The dew point is the temperature at which air becomes saturated with moisture and water vapor begins to condense into liquid.

1. **Identify the Given Values:**
- Initial Room Temperature (T1) = 20°C
- Initial Dew Point (D1) = 10°C
- New Room Temperature (T2) = 15°C

2. **Understand the Concept of Dew Point:**
