Snow has no chemical changes. It goes through a freezing stage of water vapor, just a molecular change.
Snow disappearing is a physical change. It is a combination of melting and then evaporating and of sublimation.
It is a physical change: water changes from gas to solid.
When carbon (soot) is applied to snow, it can absorb sunlight and cause the snow to melt faster. This is a physical change as the snow changes from its solid state to liquid water due to the presence of the carbon.
Not all physical changes are reversible. Some physical changes, such as breaking a glass or cutting a piece of paper, are irreversible because they result in a permanent change to the material's structure. Reversible changes, like melting ice or boiling water, are changes that can be easily reversed by altering the conditions.
Not all physical changes are reversible because most times when such changes occur parts of the substance is lost to the environment.

Walking on snow is a physical change because the snow remains as solid ice crystals and does not undergo any chemical reactions to form new substances.
