A certain mass of gas occupies 2 litres at `27^@C` and 100 Pa. Find the temperature when volume and pressure become half of their initial values .

Explanation

To solve the problem step by step, we will use the ideal gas law, which states that for a given mass of gas, the relationship between pressure (P), volume (V), and temperature (T) can be expressed as:

\[ \frac{PV}{T} = \text{constant} \]

### Step 1: Identify the given values
- Initial volume (V) = 2 liters
- Initial temperature (T) = 27°C
- Initial pressure (P) = 100 Pa
