it is a phisycal change
it is a physical change because no other chemicals are added. the only thing that makes a snowflake is water and cold. i believe the reason it takes the shape is because of the make up of the water molicule.H2O. one hydrogen and 2 oxygen
It is a physical change, from liquid to solid. The snowflake is still a form of water.
It is physical as it is a simple change of state from gas to solid.
No, it's just frozen water.

No. It is a physical change.
No not ia any way
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.
Freezing a snow man is physical change because you are not changing the chemical formulae of the snow because it's just frozen water crystals packed together to make a snow man. It's also reversible to it's original from (water). For a chemical change the formulae of the substance has changed once you have made the change (e.g baking a cake). Its also irreversible, because you cant make a cake back in flour, egg, sugar, butter, etc. -Hope this was useful
If you have to classify it, it is physical as no new substance is made. You are just moving it from one place to another.
No. It is a physical change.
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 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 .
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).
It is a physical change: water changes from gas to solid.
Changes of state are physical changes.
Snow has no chemical changes. It goes through a freezing stage of water vapor, just a molecular change.
