I am not completely sure but when things are hot-e.g boiled water, atoms are whizzing round freely like they are excited, this is partly why the water goes bubbly and boily. As for fixed objects such as a rock, the atoms are very close together and they barely move at all because they are so closely bound.
Moving on to answering your question: So if you freeze a glass of water the immediate reason should be the atoms come closer together, I have taken a wild guess but i think that this is why scientists say ice is smaller after being frozen from its normal form water/fluid [Actually, water is an exception concerning freezing. It expands due to the tetrahedral shape of hydrogen bonds between the water molecules. It produces a very rigid but "open" structure with large spaces, decreasing the density - This is why ice floats.] Therefore, at the molecular level when a substance freezes.It is kind of like slowing down what's being frozen's heartbeat.As the atoms cool they come closer together, (kind of like huddling together to keep warmth), their movements slow and they contract, ( e.g, if you were ever cold you would know how it feels, you would want to contract. Kind of like going into the foetal position. So your body would want to contract as an immediate response. The reason you aren't huddling is because your body-heat is not floating away into the atmosphere to be absorbed but is instead is absorbed by your blankets so as you contract, you slowly get back your body-heat.). So the answer is-when a substance is frozen, the molecules contract*, slowing down their movements so what was fluid is now fixed as a solid.

*The intermolecular forces and bonds increase in number and strength, "pulling" the molecules closer together.
What else can I help you with?
What happens at 0c and 100c?
0 C is 0 degrees Celsius. Pure water freezes at this temperature. 100 C is the temperature when pure water boils at sea level.
A solution is a mixture?
No, a solution is a homogeneous mixture composed of two or more substances. It is a combination in which one substance is dissolved in another, with the components being evenly distributed at a molecular level.
What is the name of the temperature at which a mixture freeze?
The temperature at which a mixture freezes is called the freezing point. For instance, water freezes at 32 degrees F. at sea level.
How is the greenhouse effect caused on a molecular level?
The greenhouse effect occurs when certain gases in Earth's atmosphere, such as carbon dioxide and methane, trap heat from the sun. These gases absorb infrared radiation emitted by Earth's surface, preventing some of the heat from escaping into space. This results in a warming effect on the planet.
What is the temperature that water freezes in celsius?
Zero degrees Celsius under normal conditions.
What is a molecular level?
Pertaining to, connected with, produced by, or consisting of, molecules; as, molecular forces; molecular groups of atoms, etc.
What happens to starch at the molecular level when it is acted upon by amylase?
the amylase degrades the starch
What happens to the molecular level when substances get hot?
When substances get hot, the molecules gain energy and vibrate more rapidly. This increase in molecular motion causes the substance to expand, changing its physical state (e.g. from solid to liquid or from liquid to gas) if the heating continues. Heating can also break the bonds between molecules, leading to chemical reactions and changes in the substance's properties.
Is Evaporation Is When Particles Escape From A Liquid?
Yes, that's basically what happens at the atomic or molecular level.
Frying an egg physical or chemical?
It is a chemical change because it is irreversible and the change happens on a molecular level.
The substance to be dissolved?
The substance that is dissolved is called the solute. It is typically added to a solvent, such as water, to create a solution. The solute gets evenly distributed throughout the solvent at a molecular level.
A mixture that is homogeneous at the molecular level?
A homogeneous mixture at the molecular level is a solution, where the solute is evenly distributed and completely dissolved in the solvent. This results in a uniform composition throughout the mixture without any visible boundaries between the components. Examples of solutions include saltwater and sugar dissolved in water.
What happens at the molecular level when a substance boils?
When a substance boils, the intermolecular forces holding the molecules together are overcome by the heat energy. This allows the molecules to move more freely and escape as a gas. The temperature at which this occurs is the boiling point of the substance.
How do you design a simple experiment to find out what happens to the volume of water when it freezes?
To design a simple experiment to observe what happens to the volume of water when it freezes, first, fill a measuring container with a known volume of water and mark the initial level. Next, place the container in the freezer until the water completely freezes. After the water has frozen, measure the new level of the ice in the container. Finally, compare the two measurements to determine if the volume of water increased, decreased, or remained the same upon freezing.
What is a molecular genetic?
Molecular genetics is the field of Biology and genetics that studies the structure and function of genes at a molecular level.
Use the word molecular in a sentence?
The cell was at a molecular level.
What happens to a substance when it dissolves in a liquid?
When a substance dissolves in a liquid, the individual particles of the substance spread out and become surrounded by the particles of the liquid. This process creates a homogeneous mixture with the substance evenly dispersed throughout the liquid. The substance retains its chemical identity, but is dispersed at a molecular or ionic level within the liquid.
