A gas is filled in a vessel at `7^(@)C`. If x fractional part escapes out at `27^(@)C`, fid x. (assuming pressure constant).

Explanation

To solve the problem of finding the fractional part of gas that escapes from a vessel when the temperature changes from \(7^\circ C\) to \(27^\circ C\) at constant pressure, we can follow these steps:

### Step-by-Step Solution:

1. **Convert Temperatures to Kelvin:**
- The initial temperature \(T_1\) is \(7^\circ C\).
- Convert to Kelvin:
\[
