you left a crayon in the window sill in the bright sunshine. It melted and is now a puddle of sticky wax. How have the properties of the crayon changed? Is this a physical or a chemical chamge? Give a reason for your answer.

A chemical property is one in which the substance has changed into another substance. The question you must answer is, "Has the crayon changed its composition?" or "Is the crayon still a crayon but just a different shape?"
