The motion of molecules is accelerated.
What else can I help you with?
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 water molecules change during freezing?
they stay in one place but the vibrate in one place instead of sliding past each other
The first law of motion describes the principle of?
during an energy change . energy is?
How does heat change the state of water?
Heat can change the state of water by increasing its temperature. As heat is added, water transitions from a solid (ice) to a liquid (water) and then to a gas (steam) through the processes of melting and evaporation. Each state change occurs at specific temperatures known as the melting point and boiling point of water.
Why doesnt molecules stop moving when diffusion does?
Molecules in a substance are always in constant motion due to their kinetic energy. Even when diffusion occurs and molecules move from areas of high concentration to low concentration, the movement at the molecular level continues due to the inherent energy present. This constant motion is maintained unless external factors, such as reaching equilibrium or a change in energy input, intervene to affect the motion of the molecules.
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.
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 molecules change during evaporation?
They go from moving around slightly, to moving around quickly and separating from one another. This is causes by evaporation.
What is happening to particle motion and thermalheat energy during melting?
Particle motion and thermal heat energy should both be increasing
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
What is the motion of solid?
The primary motion in solids is very small amplitude vibrations of atoms around their equilibrium positions. The amplitude of the vibrations increases with increasing temperature up to the melting point of the solid, at which the solid becomes liquid and far more spatial motion is possible for the molecules.
What is the motion for molecules?
The motion of molecules is random and chaotic, driven by thermal energy. Molecules vibrate, rotate, and translate in all directions, constantly colliding with each other and their surroundings. This motion is fundamental to processes such as diffusion and chemical reactions.
