A flask having a volume of 250.0 mL and containing air is heated to `100^(@)C` and sealed. Then the flask is cooled to `25^(@)C`, immersed in water, and opened. What volume of water will be drawn back into the flask, assuming the pressure remaining constant ?

Explanation

To solve the problem step by step, we will use Charles's Law, which states that the volume of a gas is directly proportional to its absolute temperature when the pressure is held constant.

### Step-by-Step Solution:

1. **Identify the Initial Conditions:**
- Initial volume of the flask (V1) = 250.0 mL
- Initial temperature (T1) = 100 °C
