A marshmallow will dissolve faster in a warm liquid, such as hot water or warm milk, compared to cold liquids. The heat helps break down the sugar and gelatin in the marshmallow, allowing it to dissolve more quickly. Additionally, liquids with higher sugar content or acidity, like soda, may also accelerate the dissolution process due to their chemical properties.
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.
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.
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.

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.
In s'mores, energy transfer occurs primarily through heat conduction and radiation. When the marshmallow is roasted over an open flame, it absorbs thermal energy from the fire, causing the sugars to melt and the marshmallow to soften. This heat is then transferred to the chocolate when the warm marshmallow is sandwiched between graham crackers, causing the chocolate to melt. Ultimately, the energy from the flame transforms into the delicious, gooey treat enjoyed by many.
A marshmallow gets hard if you warm it on the fire and then you leave it out.......It will also get hard if you leave the bag of marshmallows outside open!!!
heat energy.
No. They will melt. They are chocolate and marshmallow .
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.
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.
