Calculate the resulting temperature chagne if a 20 mL of hydrogen at `15^@C` is isobarically expanded to 21.38 m L

Explanation

To solve the problem of calculating the resulting temperature change when 20 mL of hydrogen at 15°C is isobarically expanded to 21.38 mL, we will use Charles's Law, which states that at constant pressure, the volume of a gas is directly proportional to its temperature in Kelvin.

### Step-by-Step Solution:

1. **Convert the initial temperature from Celsius to Kelvin**:
\[ T_1 = 15°C + 273.15 = 288.15 \text{ K} \]
