1.	3. A student collects wax from a burning candle. He melts it and then adds a new wick to it andleaves it to cool. Can a new and functional candle be created by this process? Why or why not?(a) Yes; it is a reversible physical change in state of wax.(b)No; it is a physical change that cannot be reversed.(c)No; it is an irreversible chemical change with the formation of a new substance.(d)Yes; it a chemical change causing the wax to change from one state to another.
Answer» ANSWER: a) YES; it is a reversible physical CHANGE in STATE of WAX.
