Certain amount of a gas occupies a volume of 0.4 litre at `17^@C` . To what temperature should it be heated so that its volume gets reduced to half pressure remaining constant ?

Explanation

To solve the problem step by step, we will use the ideal gas law, which states that for a given amount of gas at constant pressure, the ratio of the volume to the temperature (in Kelvin) remains constant.

### Step-by-Step Solution:

1. **Identify the Given Values:**
- Initial volume (V1) = 0.4 L
- Initial temperature (T1) = 17°C
- Final volume (V2) = V1 / 2 = 0.4 L / 2 = 0.2 L
