When you cook food like eggs or potatoes this is a chemical change when candle burns the wick of the candle and wax turn into nothing first put you thoughts for information and then do agree it depends or disagree explain why and how you got the answer

When you cook food like eggs, this is a chemical change. Agree.

The runny egg turns into a solid. One type of matter must be changing into another type

When you cook food like potatoes, this is a chemical change. Agree.

Boiling potatoes causes changes in the structure of the starch. Higher heat as in baking, roasting, or frying causes the development of a harder crust on the potato. This suggests that chemical changes have taken place.

When a candle burns, the wick of the candle and wax turn into nothing. Disagree.

The Law of Conservation of Mass says that you can’t turn matter into nothing. What must be happening is that the wick and the wax are changing into other substances that we can’t see, such as colourless gases of carbon dioxide and water vapour.
