Physical. It is still butter. It is still just a piece of bread. But now it is butter on a piece of bread with a bite out of it. The bread/butter is not chemically changing to form a TOTALLY new substance. For instance, when you melt butter its no longer a solid its now a liquid. Looks different, the temperature is different, and it may even taste diifferent but its still butter. But if you were to take sugar and dissolve it in water it becomes a totally different substance.

Is butter melting on warm toast a chemical or physical property?
It is a physical property. A chemical property would involve the butter reacting to the toast, but the butter is actually reacting to the heat from the toast. The butter would melt against any surface hot enough, where as butter would not melt on cold toast. Hence, the reaction to heat makes it a physical property. (A relatively easy way to remember is that physical properties deal with the transfer of physical energy or force such as heat, inertia, etc. Chemical properties occur when two material substances trade molecules or electrons.)
What are the differences between the physical and chemical?
in changes. Physical changes can be reversed. E.g. if you were to melt a block of ice, and then freeze it again, it would to some degree be reversed. This is a physical change. However, if you were to burn a peace of toast, the change would be chemical. Once the toast is burnt you cant get it back.
