What happens to the number of molecules of the gas when it is compressed?
When a gas is compressed, the volume it occupies decreases, causing the gas molecules to be closer together. The number of molecules remains the same, as no molecules are added or removed during compression.
What happens to the molecules in a substance when thermal energy is removed?
When thermal energy is removed from a substance, the molecules lose kinetic energy and slow down. This often causes the substance to cool down as the molecules have less energy to move and vibrate. In extreme cases, the substance may undergo a phase change, such as from a liquid to a solid.
Does juice lose chemical energy or kinetic energy in a freezer?
In a freezer, juice loses kinetic energy as the cold temperature slows down the movement of its molecules. The chemical energy in juice remains constant unless it undergoes a chemical change, such as freezing or thawing, which can affect its molecular composition.
What physical change happens to the water from the dye solution?
The physical change that happens to the water from the dye solution is that it gets colored. The water molecules themselves do not change chemically, but they become colored by the dye molecules that dissolve in the water.
When energy is removed from a liquid do the molecules move faster or slower?
I might be wrong, but I would say slower. If you mean energy in form of heat, molecules move slower if the liquid is colder, so if a liquid releases energy in form of heat (turns ¨cooler¨), than the molecules move slower. As I said, I might be wrong. Just my thoughts

What happens to molecules from which heat is removed?
When heat is removed from molecules, their kinetic energy decreases, causing the molecules to slow down and come closer together. This can lead to a phase change, like turning a gas into a liquid or a liquid into a solid. Cooling molecules can also result in chemical reactions slowing down or halting altogether.

What happens in a chemical change but not in a physical?
Molecules permanently change. In a physical change the effects are reversible.
What is the reaction when water is put in the freezer?
There is no reaction, only a phase change. H2O(liquid) > H2O(solid) Heat is being removed from the system.
What happens when heat energy is taken away fron molecules?
As the heat is removed, the kinetic energy of the particles decreases and they start moving very slowly. Quick reminder: kinetic energy is the energy associated with a particle's motion. The faster a particle moves, the larger its kinetic energy is.When enough energy has been removed from the system and the particles are in super slow motion, bonds begin to form between the molecules. These bonds act like glue and freeze the molecules into place.
What happens to molecules when they change from one state of matter to another?
the denseness of the molecules change(compact=solid, really far=gas, in the middle=liquid)
is solidifying water reversible?
Water solidification means freezing, that is, it turns to ice after keeping it in the freezer for some time. But it can turn back to liquid water after being removed from the freezer. Therefore, freezing is an example of reversible change.
What happens to atoms and molecules when a chemical change occurs?
They get rearranged to form new products.
What happens to the molecules of water when the temperature of the gas cools to 100C?
The molecules slow down and begin to change back to the liquid state.
What physical change happens when you put a balloon in the freezer?
The air inside the balloon will contract, so the balloon will tend to look slightly crinkled.
What happens to the molecules of water vapor when the temperature of gas cool to 100c?
The molecules slow down and begin to change back to the liquid state.
