melting butter is a physical change. which best describes what is happening?\no the butter changes into a different substance.\no the butter contains a new arrangement of atoms.\no the butter cannot turn into a solid again.\no the butter no longer contains the same number of atoms.
Answer
Brief Explanations:
In a physical change like melting butter, the substance's chemical composition remains the same. There is no new substance formed, no new atom - arrangement, and the number of atoms stays constant. Also, melted butter can solidify again.
Answer:
None of the above options are correct. In a physical change of melting butter, the butter's chemical identity remains unchanged. It is just changing from a solid to a liquid state due to heat - energy increasing the kinetic energy of its molecules and changing their intermolecular forces. If we must choose from the given options, all are incorrect as they describe chemical - change characteristics rather than physical - change ones.
