Is a toast a chemical or physical change?
Chemical
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.)

Is burning toast a chemical change or a physical change how do you know?
It is kind of both....The chemical: The toast loses its water molecules and so loses most of its H2O.The Physical: The toast becomes hard and crunchy from soft and airy.Added:The toast burning is a total physical change, not chemical. Water loss from the toast is not a chemical change as species have not changed partners ( atoms have not rearranged into new species ) and H2O remains the molecule H2O, water.

Is burning toast a physical change?
Burning toast would be a chemical change. The bread would be changed into carbon and the reaction can not be reversed.
