The walking is not a change at all.
The snow experiences a physical change (it gets compressed, and some crystals may melt due to the pressure).
NO
Changes of state are physical changes.
Yes. The act of moving a substance from one location to another is a physical one. The act of changing the state of the substance from one state to another can be physical also. But the act of altering the substance by adding or subtracting one or more of its components is a chemical change.
physical properties of coal and snow
Water
Ask yo' teacher!! :D Cheer Uhp ii8? =D
No. It is a physical change.
Snow disappearing is a physical change. It is a combination of melting and then evaporating and of sublimation.
physical, because there is no chemical reaction to cause the change. it's just heat.
Yes There Is.....
No not ia any way
Melting of ice with salt is example of physical change as there is no chemical reaction involved .
It is a physical change: water changes from gas to solid.
Changes of state are physical changes.
Precipitation in weather terms (rain, snow, etc.) is a physical process. Precipitation in chemical terms (e.g. lead iodide falling out of solution) is a chemical change.
Snow has no chemical changes. It goes through a freezing stage of water vapor, just a molecular change.

milk going sour is a chemical change because it can't be reversed. Most physical changes can be reversed for example snow melting is a physical change because it can freeze again.
