A bucket full of water is placed in a room at `15^(@)C` with initial relative humidity 40%. The volume of the room is `50m^(3)`.(a) How much water will evaporated? The saturation vapour pressure of water at `15^(@)C`and `20^(@)C`are 1.6kPa and 2.4 kPa respectively.

Explanation

To solve the problem step by step, we will follow the reasoning provided in the video transcript.

### Step 1: Calculate the initial vapor pressure
The initial vapor pressure can be calculated using the formula:
\[ \text{Vapor Pressure} = \text{Relative Humidity} \times \text{Saturation Vapor Pressure} \]
Given:
