How does the motion of the molecules change evaporation?
They go from moving around slightly, to moving around quickly and separating from one another. This is causes by evaporation.
How does the motion of the molecules change during melting?
The motion of molecules is accelerated.
Do molecules stay the same during physical change?
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.
How does the motion of molecules change during freezing?
It becomes much more restricted.
What properties of water allow it to exist as a liquid in oceans and rivers?
Its molecules are in constant motion, allowing for evaporation and condensation.
When matter changes from one phase to another what happens to the motion of molecules and how does it impact the spacing of the molecules?
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
How does the motion of the gas molecules change?
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.
How does the motion of the water molecules change during freezing?
they stay in one place but the vibrate in one place instead of sliding past each other
What happens to molecules during friction?
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.
What is a change of position during a unit of time called?
motion
What are moving molecules?
Molecules in motion
How are evaporation kinetic energy related?
kinetic theory of matter for evaporation is that when we heated liquid suppose water consistantly so at 100 it becomes boil and afterthat changes into vapour as a result the molecules move far away from one another their kinetic energy increases because the motion between them increases the attraction going to be weak and at the end the higher energy molecules escape from the surface of water...that is the real phenomena that happens when evaporation occurs..
