A sample of gas is taken in a closed vessel at `20^(@)C`. The gas is heated until the pressure and volume is doubled. What is the final temperature?

Explanation

To solve the problem step by step, we will use the ideal gas law, which states that:

\[ \frac{P_1 V_1}{T_1} = \frac{P_2 V_2}{T_2} \]

### Step 1: Identify the initial conditions
- Initial pressure (\(P_1\)) = \(P\) (unknown)
