A. The pentane molecules move randomly in all directions to fill their
container.
O
B. The pentane molecules move past one another but are held close
together.
O C. The pentane molecules are locked in one place and do not move.
O D. The pentane molecules vibrate and are fixed in one position.

Respuesta :

In the liquid state, the pentane molecules move past one another but are held close together.

What is the liquid phase?

The liquid phase is a phase of matter that is made of molecules that in motion but do not posses as much kinetic energy as the molecules of gases. Thus implies that the molecules are able to translate.

Hence, the pentane molecules move past one another but are held close together.
