State Henry's law. What is the effect of temperature on the solubility of a gas in a liquid ?

Explanation

### Step-by-Step Solution

**Step 1: State Henry's Law**
Henry's Law states that at constant temperature, the solubility of a gas in a liquid is directly proportional to the partial pressure of the gas above the liquid. This can be mathematically expressed as:
\[ P = k_H \cdot x \]
where:
- \( P \) is the partial pressure of the gas,
- \( k_H \) is the Henry's law constant (which varies with the nature of the gas and the solvent),
