low energy particles that experience no attractive forces between them.
high energy particles that experience high attractive forces between them.
high energy particles that experience little attractive force between them
Which of the following statements is true regarding the particle structure of liquids? Particles of a liquid are:
very close together, so the liquid cannot easily change its shape.
fast-moving, so they fill the volume of their container.
relatively close together, so they cannot be easily compressed.
very far apart, so they have plenty of room to move around.
