Yes, it is true.
Toasting a marshmallow is actually a chemical change. The marshmallow becomes black and crispy, it also no longer tastes the same. Thus, it is a chemical change.Roasting a marshmallow is an example of a chemical change. Generally when you heat food in the process of cooking, you will cause a chemical change.
Yes
It depends on how long you roast it! If you simply allow it to warm up, it is still a marshmallow after roasting, so it is a physical change. If you like it crispy and burnt, it is a chemical change because it starts off white and then it eventually melts and turns brown. This browning is oxidation, a chemical process where some of the marshmallow's sugar is burnt and carbon dioxide is released into the air.
The answer is physical because in physical they are 5 senses see, hear, touch,smell. The toasted marsh mallow you can taste it, smell it when you are far, touch it when you eat it, you can hear it when it comes out of the oven,and you can see it when it's on your plate.
To Answer your question, it can be reversed, but it not so easy. Look at what I found in an article: "Physical changes, like the melting of a solid to a liquid can be reversed easily - just refreeze it. Chemical changes, like the blackening of toast when burnt, are not so easy to reverse."

Chemical Change :)
Physical change.
Yes, anything that burns (combust) is a chemical change
Yes
chemical change
Because the chemical composition is modified.
physical
There is a chemical change in a marshmallow when it is roasted because was once white and colder and than when it gets roasted it turns like a blackish-brown and burning hot.

Yes. You still have marshmallow at the end of the cut so it must be physical. If you burnt the marshmallow, that would be chemical.
