Burning a marshmallow is a chemical reaction called combustion where a substance containing carbon and hydrogen (in the presence of oxygen) breaks down to form the products carbon dioxide and water. A marshmallow is composed mainly of sugar with a chemical composition of C6H12O6; where you might notice that the ratio of hydrogen to oxygen is two to one (2:1), the same ratio of hydrogen to oxygen in water (H2O). Ideally, all the water would be burned off and you would be left with pure carbon after the combustion reaction.

Is a burning a marshmallow a physical or chemical change?
chemicalBurning a marshmallow is a chemical change.
Is charring a marshmallow a chemical or physical change?
Charring a marshmallow is a chemical change because the heat causes the sugars in the marshmallow to break down and react with oxygen in the air, producing new substances. This results in a change in the chemical composition of the marshmallow.
Why is a candle melting a marshmallow a chemical change?
Because the chemical composition is modified.
When you roast a marshmallow is it a physical change or a chemical change?
Roasting a marshmallow is a physical change, not a chemical change. The marshmallow undergoes a change in its physical state as it is heated, but its chemical composition remains the same.

How does white paper effect cooking a marshmallow in a solar oven?
The use of parchment paper would help prevent burning of marshmallow in an oven in general. This applies to solar ovens and stove ovens.
What kind of heat transfer is a marshmallow over a bonfire?
The heat transfer involved when a marshmallow is roasted over a bonfire is primarily conduction. The heat from the flames directly heats the marshmallow through direct contact, causing it to melt and become gooey.
