Which of these changes is an example of a physical change?
A. burning logs
B. lighting a firework
C. melting cheese
D. rusting nail

Asked by ann0146

Answer (1)

Melting cheese is a physical change because it alters the state of the cheese without changing its chemical composition. In contrast, burning logs, lighting a firework, and rusting nails are all chemical changes, as they result in new substances being formed. Identifying the differences between these changes helps in understanding the properties of matter. ;
