A balloon is filled with one mole of helium at `0^@C` and 1 bar pressure. It will burst if pressure is decreased to 0.2 bar. What is the maximum volume of balloon?

Explanation

To solve the problem of finding the maximum volume of a balloon filled with one mole of helium at 0°C and 1 bar pressure, which bursts if the pressure decreases to 0.2 bar, we can use the ideal gas law and Boyle's Law. Here’s a step-by-step solution:

### Step 1: Understand the Ideal Gas Law
The ideal gas law is given by the equation:
\[ PV = nRT \]
Where:
- \( P \) = pressure
- \( V \) = volume
