Question

Is melting butter in the sun a chemical or physical change?

Answer 1

Melting butter in the sun is a physical change.

Step-by-step explanation:

Physical changes are the alterations in the form or state of matter that do not involve a change in the substance's chemical composition. Examples include changes in size, shape, color, or state which is solid to liquid to gas, without the creation of a proper new substance.

For the given case, melting butter in the sun is a physical change. A physical change is a change in the state or appearance of a substance without changing its composition. When butter melts in the sun, it changes from a solid to a liquid state, but the molecules of the butter remain the same.

Answer 2

Hello.


A chemical change is always associated with the change of the chemical components.

A physical change is associated with the change of the estate(solid, liquid, gaseous).


We can infer that when the butter melts in the sun, we have the state change solid → liquid, but it is still butter. Therefore, the melting is a Physical Change.
