What happens to particles at the molecular level when water freezes?

The particles' movements slow down. Particles (or atoms) contain energy; the more energy the particles have, the more the particles move. However, there is a certain level of energy at which the bonds between the particles break; this energy is called bond energy. For example, take a boiling pot of water. At the atomic level view, heat is equal to energy; the heat is transferred from the flame to the H2O molecules, giving them more energy and making them move faster. The the H2O molecules break apart, turning to hydrogen and oxygen gas. In an ice cube, the heat/energy is taken from the H2O molecules, slowing them down and creating a packed solid.

What happens at the molecular level when NaOH dissolves in HCl?
Increase
What do solutions and suspensions have in common?
Both solutions and suspensions are mixtures of two or more components. However, the particles in suspension are larger and will eventually settle out, where the particles in a solution are on the atomic or molecular level.
Why do particles in a colloid remain dispersed throughout the mixture?
The solute particles in a colloid are so small that they remain suspended. While not combined at the molecular level, they are so fine that they cannot be separated by normal means.
What happens during condensation and sublimation?
Particles increase their motion because of increased kinetic energy on the molecular level. This breaks bonds holding them together as a solid and the particles become gases during sublimation. During condensation the opposite occurs. Particles are losing heat energy which means a loss of kinetic energy slowing the particles down to the point that the attractive forces form bonds causing the gas to become a liquid.
A mixture that is homogeneous at the molecular level?
By definition, a homogeneous mixture is a substance that is uniform at the molecular level. An example of this is salt water.
Is Evaporation Is When Particles Escape From A Liquid?
Yes, that's basically what happens at the atomic or molecular level.
Is it true that solution particles do not mix at the atomic or molecular level?
is it true

What is the change in molecular movement when water evaporates?
what happens at the molecular level when water evaporates?
What happens at the molecular level when a substance boils?
The state of matter changes from a liquid to a gas. (But the one word answer that the assignment is looking for is vaporization.)
What happens to starch at the molecular level when it is acted upon by amylase?
the amylase degrades the starch
Does heat flow because of expansion or collision between particles in matter?
many many collisions at the atomic/molecular level
How mixture different from a solution?
A solution is a type of mixture at the molecular/atomic level. Mixtures that are not solutions usually contain particles visible at either the microscopic or macroscopic level.
What happens to the motion of molecules of matter when an object gains or loses thermal energy?
Increasing temperature means increased kinetic energy on the atomic or molecular level. Temperature of a given substance is the average kinetic energy of the particles of which that substance is composed.
What does heat result from?
Heat is random motion or vibrations that take place on an atomic or molecular level. The faster particles are moving, the hotter they are.
Frying an egg physical or chemical?
It is a chemical change because it is irreversible and the change happens on a molecular level.
What do solutions and suspensions have in common?
Both solutions and suspensions are mixtures of two or more components. However, the particles in suspension are larger and will eventually settle out, where the particles in a solution are on the atomic or molecular level.
