Which of the following is not correct?

Options

A. Enthalpy of physical adsorption is less compared to enthalpy of chemical adsorption
B. Milk is an example of emulsion
C. Physical adsorption increases with the increase in temperature
D. Smoke is an aerosol

Explanation

To determine which of the statements is not correct, let's analyze each option step by step:

### Step 1: Analyze Option 1
**Statement**: Enthalpy of physical adsorption is less compared to enthalpy of chemical adsorption.

**Explanation**: This statement is correct. In physical adsorption, the interactions are due to weak Van der Waals forces, leading to lower enthalpy changes. In contrast, chemical adsorption involves the formation of strong chemical bonds, resulting in higher enthalpy changes. Therefore, the enthalpy of physical adsorption is indeed less than that of chemical adsorption.
