The atoms in a sample are close together but can slide past one another. as the atoms lose energy, they move slower. the atoms become locked in place because of attractive forces between themwhich change of state is taking place?

Explanation:

As we known that atoms in a liquid substance are closer to each other and they are able to slide past each other because the attractive forces between them are neither too strong or too weak.

Hence, liquid substance are able to take the shape of a vessel in which they are placed. Liquids have a fixed volume but no fixed shape.

On the other hand, atoms of a solid do not have enough kinetic energy. As they are held by strong attractive forces and they only vibrate at their mean position.

Hence, solids have fixed shape and volume.

Thus, we can conclude that in the given situation liquid to solid change of state is taking place.

When they are close together and can slide, it will be in the state of a liquid, which takes a particular volume, but not a form.

When energy is decreased, the atoms move slower, and eventually locked in place, which will give it a fixed form, i.e. a solid.

The change of state is therefore that from a liquid to a solid, i.e. freezing.

mechanics (greek   is that area of science concerned with the behaviour of physical bodies when subjected to forces or displacements, and the subsequent effects of the bodies on their environment. the scientific discipline has its origins in ancient greece with the writings of aristotle and archimedes[1][2][3] (see history of classical mechanics and timeline of classical mechanics). during the early modern period, scientists such as galileo, kepler, and newton laid the foundation for what is now known as classical mechanics. it is a branch of classical physics that deals with particles that are either at rest or are moving with velocities significantly less than the speed of light. it can also be defined as a branch of science which deals with the motion of and forces on objects. the field is yet less widely understood in terms of quantum theory.
