The temperature of a given mass of air was changed from `15^(@)C` to `-15^(@)C`. If the pressure remains unchanged and the initial volume was `100 mL`, what should be the final volume?

Explanation

To solve the problem step by step, we will use the ideal gas law and the relationship between volume and temperature when pressure is constant.

### Step 1: Identify the given values
- Initial temperature (T1) = 15°C
- Final temperature (T2) = -15°C
- Initial volume (V1) = 100 mL

### Step 2: Convert temperatures to Kelvin
