Is toasting marshmallow a chemical or physical change?
Toasting a marshmallow is a chemical change because the heat causes the complex sugars in the marshmallow to caramelize and change their chemical structure. This results in the marshmallow turning brown and gaining a different taste and texture.
Radiation is the type of heat roasts the marshmallows?
When roasting a marshmallow the transfer of heat from the flame to the marshmallow is radiation.Radiation is the transfer of heat through energy waves. It can actually be considered conduction as well if you place the marshmallow into the flame, since that is the direct transfer of heat.
Marshmallow cooked by fire what heat transfer does it use?
When a marshmallow is cooked over a fire, it uses the heat transfer method of conduction. The heat from the fire is directly transferred to the marshmallow through direct contact, causing it to melt and cook.
What happens to the volume of a marshmallow when you heat up particles?
When you heat up particles in a marshmallow, the particles gain energy and move faster. This causes the marshmallow to expand as the air trapped inside heats up and expands, increasing the volume of the marshmallow.
What is the effect of heat on a marshmallow?
smoke and burn
What energy transformation takes place when roasting a marshmallow?
When roasting a marshmallow over a fire, chemical energy stored in the marshmallow is converted to thermal energy as the marshmallow heats up and starts to melt and brown. This is an example of energy transformation from chemical energy to thermal energy.
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.
What energy comes out of a marshmallow when it is burned?
heat energy.
What is the best recipe for making marshmallow-topped brownies?
To make marshmallow-topped brownies, bake a batch of brownies according to your favorite recipe. Once the brownies are done, top them with a layer of marshmallows and broil them in the oven until the marshmallows are golden brown. Enjoy your delicious marshmallow-topped brownies!
How can I make a delicious marshmallow sauce?
To make a delicious marshmallow sauce, combine marshmallows, butter, and milk in a saucepan over low heat. Stir until melted and smooth. Add vanilla extract for flavor. Drizzle over desserts or use as a dip.
At what heat does a marshmallow get warm at?
100 degries
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.
