It is desired to reduce the volume of 1000 cm of a gas by `25%`. To what temperature the gas be cooled if the initial temperature is `125^@C` and the pressure remains constant ?

Explanation

To solve the problem of reducing the volume of a gas by 25% while keeping the pressure constant, we can use Charles's Law, which states that at constant pressure, the volume of a gas is directly proportional to its temperature in Kelvin.

### Step-by-Step Solution:

1. **Identify the Initial Conditions:**
- Initial Volume (V₁) = 1000 cm³
- Initial Temperature (T₁) = 125°C
