because the chocolate dissolves the marshmallows inside to the outside
heat i think
This is convection. Convection is the effect you get when hotter parts expand and have lower density than cooler parts. What you describe is "melting", with the temperature of the surrounding liquid being higher than the temperature of the marshmallow. So, heat flows from the hotter region to the cooler by conduction and eventually the temperature reaches the melting point.I'd suggest re-arranging that.Conduction transfers the cocoa's heat into the marshmallow, cooling the liquid in doing so.Convection helps to maintain the process by replacing the cooled cocoa with hot.When you place any chocolate in any fluid at a higher temperature than the melting point of chocolate, the chocolate will melt. Likea lump of ice in warm water. Convection playsno role at all- if you prevent convection by packing the fluid with small pebbles etc, the marshmellow will still melt. The heat is transferred by conduction, not convection.
Poke him with a lit match or other device, if he melts he's part marshmallow.
the reason why chocolate melts because it contains coco butter and because its has less cocoa solid
When a solid melts, it is due to an increase in thermal energy to the temperature at which it melts.
When an ice cube gains energy, it is the same as gaining heat. So if an ice cube is getting warmer, it melts.
heat
"absorb" When ice melts the particles of water -absorb- energy.
Think about setting each of them out on the kitchen counter for an hour. After an hour, will the ice cube be melted or the marshmallow?
Melting and boiling (vaporization) absorb energy, freezing and condensing release energy.
No. When a substance melts it absorbs energy.
It is false that an ice cube melts when it's mechanical energy increases.
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.
