One mole of an ideal gas at `25^(@)C` is subjected to expand reversible ten times of its initial volume. The change in entropy of expansion is

Explanation

To solve the problem of calculating the change in entropy for the expansion of one mole of an ideal gas, we can follow these steps:

### Step 1: Understand the formula for change in entropy
The change in entropy (ΔS) for a reversible process can be expressed as:
\[ \Delta S = \frac{Q_{\text{reversible}}}{T} \]
where \(Q_{\text{reversible}}\) is the heat exchanged during the process and \(T\) is the absolute temperature in Kelvin.
