Multiple choice

What is the significance of the van der Waals equation in the study of liquids?

  1. It provides a simple model for the behavior of real gases

  2. It can be used to predict the critical point of a liquid

  3. It relates the pressure, volume, and temperature of a liquid

  4. It determines the viscosity of a liquid
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The van der Waals equation is a simple model for the behavior of real gases and liquids, and it can be used to predict the critical point of a liquid, where the liquid and gas phases become indistinguishable.
