Is marshmallow toasted a chemical change?

Well, maybe not burnt — but definitely toasted. Heating the marshmallow over the fire can make the sugar caramelize, a chemical reaction that produces the brown color and toasted flavor.

What type of change is the outside of the marshmallow undergoing?

If the marshmallow completely burns, it undergoes color changes, because marshmallows are mainly made of sugars and other substances that cook or burn. This burning/cooking produces new substances in the marshmallow’s crust. It produces caramel. This represents a chemical change.

What happens when a marshmallow is toasted?

When marshmallows are toasted, a chemical change occurs. The sugar molecules in the marshmallow are being changed into carbon (1). Sugar can be changed into water molecules. When you toast marshmallows, the heat causes a chemical reaction producing water molecules which then evaporate, leaving the carbon behind (4).

Is roasting a marshmallow convection or radiation?

Burnt marshmallow is simply a marshmallow that has been extremely toasted! There are two main processes that heat a marshmallow: absorption of campfire radiation (photons) and contact with very hot air rising off the fire (convection). It also forms a crust that helps the marshmallow keep its form.

What do you call a toasted marshmallow?

S’mores are usually made by the campfire. Marshmallows are roasted over the fire until they’re gooey. Then graham crackers with pieces of a chocolate candy bar are used to sandwich the gooey roasted marshmallow. Many kids mash the combination together so that the heat from the marshmallow will melt the chocolate.

What does it mean when a marshmallow is toasted?

A marshmallow toasts when sugar on the surface is exposed to high heat. It IS a chemical reaction called caramelization. Caramelization is the browning of sugar.

How is the browning of a marshmallow a chemical change?

A marshmallow toasts when sugar on the surface is exposed to high heat. It IS a chemical reaction called caramelization. Caramelization is the browning of sugar. The brown colours are produced by three groups of polymers: caramelans (C24H36O18), caramelens (C36H50O25), and caramelins (C125H188O80).

How are marshmallows toasted in a campfire?

Luckily, with a little science, you can avoid the singe and get mallows that are uniformly brown and perfectly gooey every time. Here’s how: In every campfire, there are three types of heat transfer going on: conduction, convection and radiation.

Do you know the science behind roasting marshmallows?

Michigan State University Extension recommends using the science behind roasting marshmallows as a great way to incorporate science education. Here are some questions that you can ask as well as links to help answer the questions: Why do marshmallows burn (or catch on fire) so easily?
