State whether the following processes is exothermic or endothermic : `H_2O (l) to H_2O (s) , Delta H = - 6.01 kJ `

Explanation

To determine whether the process of converting liquid water (H₂O) to solid water (ice) is exothermic or endothermic, we can analyze the given information step by step.

### Step-by-Step Solution:

1. **Identify the Process**: The process given is the conversion of liquid water (H₂O (l)) to solid water (H₂O (s)), which is the freezing of water.

2. **Understand the Sign of ΔH**: The problem states that ΔH = -6.01 kJ. The ΔH value represents the change in enthalpy during the process.
