When water and sugar are mixed together thoroughly the water molecules and sugar molecules will?
Change phaze
Is dissolving powder into water a chemical change?
No, dissolving powder into water is a physical change, not a chemical change. The powder molecules are still the same chemical compounds as they were before dissolving, just dispersed in the water molecules.
Is there more water molecules in thermal energy when its hot or cold?
The number of water molecules is not dependent on temperature.
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.
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.
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.
Is dissolving NaCl in h2o a chemical change?
Dissolving NaCl in water is a physical change, not a chemical change. The NaCl molecules remain the same chemically, but the arrangement of the particles changes as they interact with water molecules.
Is sugar dissolving in water physical change or chemical?
It is a physical change as you can change it back.
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 is freezing water to make ice cubes a physical change?
Freezing water to make ice cubes is a physical change because it involves a change in state from liquid to solid without altering the chemical composition of the water molecules. The molecules in water reorganize to form a crystalline structure when frozen, but they remain the same H2O molecules.
What happens when sucrose is dissolved in water?
When sucrose is dissolved in water, the sucrose molecules break apart into individual glucose and fructose molecules. These individual molecules become surrounded by water molecules, forming a solution. This process is a physical change, as the chemical composition of the sucrose molecules remains the same even though they are now dispersed throughout the water.
Why is boiling water a physical change?
Boiling water is a physical change because it doesn't change the chemical composition of the water molecules. The water molecules simply gain enough energy to break away from their liquid state and become a gas, without any new substances being formed.
