Answer: Liquid in gas.
- A Solid in liquid
- B Liquid in gas
- C Gas in liquid
- D Solid in solid
Correct answer: B. Liquid in gas
Explanation: Fog consists of tiny liquid water droplets dispersed in air (a gas), making it an aerosol of liquid in gas.
A typical adsorption isotherm: x/m (mass adsorbed per gram of adsorbent) rises steeply at low pressure, then flattens into a saturation plateau as the adsorbent surface fills up.
