Arrange the following in the order of increasing entropy:

Options

A. `1mol of H_(2)O(s) at 0^(@)C` and `1atm` pressure
B. `1mol of H_(2)O(s) at 0^(@)C` and `0.8 atm`pressure
C. `1 mol of H_(2)O(l) at 25^(@)C` and `1 atm` pressure
D. `1 mol of H_(2)O(l) at25^(@)C` and 0`.8 atm` pressure

Explanation

To arrange the substances in the order of increasing entropy, we need to consider the factors that affect entropy: volume, temperature, and pressure. Here’s a step-by-step solution:

### Step 1: Understand the Factors Affecting Entropy
Entropy (S) is a measure of disorder or randomness in a system. It is influenced by:
- **Volume**: Greater volume leads to higher entropy as molecules have more space to move.
- **Temperature**: Higher temperatures increase the kinetic energy of molecules, leading to greater disorder and thus higher entropy.
- **Pressure**: Higher pressure decreases volume, which reduces the space available for molecular movement and thus decreases entropy.
