It is a physical change.
Melting butter in a pan is a physical change. It involves a change in state from solid to liquid without altering the chemical composition of the butter.

Popcorn with butter is a mixture. The popcorn and butter retain their individual properties and can be physically separated.
The physical properties of butter include soft and in some cases, liquid. This depends on what type of butter it is.
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.)
physical change
physical because it can return to its solid state by cooling. chemical changes can not be reversed so easily
No, because you are not changing the state of matter. All that you are doing is just a physical change, because the butter is not changing at all.
The act of popcorn popping is a physical rather than chemical change. Air within the popcorn seed is heated, causing it to build up to higher pressure than the air outside. As a result of this, the air is explosively released to the area of lower pressure, in effect popping the popcorn.
Melting butter in a pan is a physical change. It involves a change in state from solid to liquid without altering the chemical composition of the butter.
Melting of butter is a physical change.
Melting butter is a physical change because it involves a phase change from a solid to a liquid without altering the chemical composition of the butter.
Physical.
Its called butter popcorn or cheese popcorn
Melting butter is a physical change because the butter retains its chemical composition while transitioning from a solid to a liquid state.
it is a physical change
Melting is a physical change; but above a temperature the thermal decomposition of butter begin - this is a chemical change.
