Is melting cheese a physical or chemical change it's for science

Answers

In the given question, melting cheese is a type of physical change.

A physical change is defined as a change in the physical properties of a substance, such as its shape, size, or state, without changing its chemical composition.

When cheese is melted, it changes from a solid to a liquid state, but its chemical composition remains the same. The molecules in the cheese are simply rearranged as it is heated, causing it to melt.

Therefore, melting cheese is a physical change. This is because the cheese changes from a solid to a liquid state, but its chemical composition remains the same.
