Hello There!
Physical changes can be reversed whereas chemical changes can not.
Rain turning to snow is a physical change.
The snow could certainly be changed back into rain.
An example of a chemical change is making toast.
Once the toast is made, it is not possible to reverse.
In short, it is a physical change.
Hope This Helps You!
Good Luck :)
