When water and sugar are mixed together thoroughly the water molecules and sugar molecules will?
Change phaze
Is there more water molecules in thermal energy when its hot or cold?
The number of water molecules is not dependent on temperature.
How come water doesnt change as it melts from solid to liquid water?
Water does change as it melts from a solid to liquid. That's the change. Its molecules speed up and separate from the lattice structure structure of the ice and become fluid. This is called a physical change because the water molecules themselves do not undergo a change. Solid water and liquid water are still water.If you're talking about temperature, the temperature does not change during the phase change. That's because the heat energy is being used to remove water molecules from the lattice structure. Once all of the water molecules a separated, the temperature can increase.
Is the amount of water the same after the solid ice change phase to its initial form as an ice water?
A phase change does NOT chance the total number of molecules. There will be some evaporation and sublimation too. During the time that ice melts there will some molecules that sublimate to water vapor and also some water molecules evaporate to vapor. But the total mass and number of molecules will not change.
Dissolving liver salts in water leads to a physical change?
This is a physical change because the liver salt molecules and the water molecules haven't changed - they have just intermingled.
Molecules in what state are strongly attracted to each other but can change positions?
I think it is water molecules
Why did the number of the water molecules on each side of the membrane change where as the number of sugar molecules stayed the same?
The membrane is permeable to water but not to sugar.
How do water molecules in the solid phase compare with water molecules in the gaseous phase?

What will happen to the water molecules when water boils?
It's actually a lot simpler than that. When liquid water boils, some of the water molecules in a liquid state become so energetic that they go into a gaseous state. They remain water molecules, completely unchanged in their internal composition. They just change how they relate to other molecules. The only "gas" that's released during boiling is water vapor. As such, you can reheat the same water a thousand times and you won't get any change in the boiling process (other than loss of the liquid as the water vapor wisps away). The water molecules in a liquid state will become water molecules in a gaseous state, and the process will be the same on the first, second, and thousandth time.
What does evaporartion mean?
the water molecules get to a certain temp that they change form
Why is water evaporating in the atmosphere a physical change?
Because the chemical nature of water molecules is unchanged.
What happens to snow molecules during phase change?
The snow (solid) become water (liquid); the distances between molecules are decreased during the change of phase.
