Question

Which of the following best describes the motion of particles in a liquid?

• A. Completely static
  
• B. More freely moving as compared to gases
• C. Less freely moving as compared to solids
• D. More freely moving as compared to solids

Answer 1

The correct option is D More freely moving as compared to solids

In liquids the molecules are not closely packed, they have more intermolecular space and take the shape of the container. But the molecules are not as free as in gases. Molecules in a gas have a great distance between each other and move in all directions. Whereas particles in solid are compact and do not move. Therefore, the properties of liquids lie somewhere between those of solids and gases.
