It becomes much more restricted.
The motion of molecules is accelerated.
they stay in one place but the vibrate in one place instead of sliding past each other
Yes, during a physical change, molecules remain the same. The arrangement and motion of molecules may change, but the actual atoms that make up the molecules do not change.
the force of attraction between its molecules becomes strong enough to overcome the energy of motion that its molecules have when the substance is in its liquid state, molecules are locked into rigid crystalline formations.
The freezing of water is a physical change. The water stays the same compound.
They go from moving around slightly, to moving around quickly and separating from one another. This is causes by evaporation.
Yes, molecules are in constant motion. This motion is known as Brownian motion, where molecules move randomly due to their kinetic energy. This movement is essential for processes such as diffusion and chemical reactions.
it depends on which way its heading on the scale, if it's becoming more solid the atoms are moving less and compressing together if it' becoming more gaseous the atoms are moving more and expanding
Gas molecules change their motion when they bounce into the surfaces of their containers. If the surfaces absorb the impact, then energy is transfered out of the system and particle speed decreases.
The molecules are kept in the liquid state by being above freezing temperture and below the vaporization temperture. They take the energy needed to stay in this form from their surroundings and if their surroundings are above freezing temperture and below vaporization temperture they will stay in the liquid state theoretically forever.
During friction, molecules at the contact surfaces interact with one another. The force of friction causes these molecules to resist motion, generating heat in the process. This heat is a result of the molecules vibrating and colliding with each other.
