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.
