It's Peggy Sue's birthday and she's about to blow out the candles on her cake. Brother Roger stops the party when he shouts: "Look at that! Chemical and physical changes taking places on your birthday cake!" How would you respond to Roger? A) Roger is incorrect. The melting wax is a physical change but there is no chemical change taking place. B) Roger is correct. Lighting the match is a chemical change and burning the candles is a physical change. C) Roger is correct. The melting wax is a physical change and the burning candle wick is a chemical change. D) Roger is incorrect. Only a chemical change is taking place as evidenced by the light and heat of the burning candles.

I believe it is C since melting is a physical change and burning is a chemical but someone might want to check my answer.

OpenStudy (anonymous):

melting is physical

OpenStudy (anonymous):

So it is C?

OpenStudy (anonymous):

burning is chemical so ya C is the right answer
