Butter melting= physical change
Egg whites hardening= chemical change

A physical property is a measurable characteristic of an item that is determined by its appearance. A sentence with it would be "More than one physical property of the substance changed when it became a gas."
Yes, evaporation is a physical change because it is a process in which a liquid changes to a gas without any change in its chemical composition.
Magnetization of a needle is a physical change because it does not involve any chemical reactions. The alignment of the magnetic domains within the needle is rearranged to make it magnetic, but the composition of the needle remains the same.
because structural characteristic do not change over time but physical appearance do
Rotting is a chemical change, as it involves the decomposition of organic matter through biological or chemical processes. It results in the formation of new substances, such as gases and compounds, rather than just a rearrangement of the original materials.
physical change
Grinding coffee beans is a physical change as it does not change the chemical composition of the beans.
When a cake is baked it changes its physical appearance and is thus said to undergo a physical change.However there are many concurrent chemical changes:sugars caramelizeproteins coagulateleavening agents (baking soda etc.) release carbon dioxidestarches, oils and fats oxidize
pretty sure its a chemical change.
