The physical properties of butter include soft and in some cases, liquid. This depends on what type of butter it is.
1. soft
2. yellowish white
3. greasy
4. smooth
There's an easy way to tell whether a property is physical or chemical: if you reverse it, do you get back what you started from? If you do, it's a physical change.
It is a physical property since the butter is still butter.
Butter is flammable.
It's delicious and yellow.
Melting is a physical change.
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.)

This is a purely chemical reaction. The reason why is simply because bacteria in the butter is turning the lactose and sugars found in butter into lactic acid.

physical change
Physical, because the stuff that the butter is made out of doesn't change, just the state, or physical form, that it is in. (solid to liquid.)

it is a physical change
Melting butter is a physical change. Although the state of matter changes(solid into liquid), it is still the some substance.
Melting is a physical change; but above a temperature the thermal decomposition of butter begin - this is a chemical change.
