The chocolate undergoes a state change from solid to liquid as its temperature exceeds the freezing point of the chocolate. Chocolate molecules are liberated into the air. When the molten chocolate is transferred to a food item, or to a mold, a heat transfer from the chocolate to the item it was placed on or in takes place, followed by a state change from liquid to solid as the temperature of the chocolate is reduced below its freezing point. When the chocolate is placed in the mouth of a chocolate eater, acetylcholine and cholinesterase transmitted along the nerves leading from the taste buds to the brain signal to the brain that something tasty has been consumed. This leads to release of various biochemical transmitters that signal satisfaction, unless you buy really cheap chocolate and then these same transmitters will signal, "what the hell were you thinking, the good stuff was only a buck more!" Some people who melt chocolate experience temporary enlargement of the bank account since chocolate, properly melted and formed into salable products, is a valuable and desirable item of commerce. Caution must be exercised since excessive melting of chocolate can lead to increased mass in the chocolate melter. A gooey amazingness that can go on pretty much anything edible. Or an oozing, flowing, melted, liquid gold that you can eat. Look up "tempering chocolate." Check Related Links for a cool website, if you are interested in chemistry or experiments with chocolate.
Most any kind of chocolate, when melted and tempered properly, can be molded.
Ice melting is the phase change of solid ice into liquid water due to an increase in temperature, whereas chocolate melting is the phase change of solid chocolate into liquid chocolate also due to an increase in temperature. The main difference is that ice melting is a pure substance changing phases, while chocolate melting involves a mixture of ingredients such as cocoa butter, sugar, and milk solids.
Most any kind of chocolate, when melted and tempered properly, can be molded. Do not use cooking chocolate, it's not the greatest for eating.
physical change
No, you can take the melted chocolate goo and pour it into a mold, cool it and re-form the candy bar. No, melting a chocolate bar is not an irreversible change. Melting a chocolate bar is just changing its state of matter. If you but the melted chocolate bar in a freezer, where exothermic processes will occur, and the chocolate bar will be solid again.
Yes. It's just like ice to water and back to ice. - - - - - "Reaction" implies a chemical change. Melting chocolate is a physical change. (Hardening melted chocolate can involve a whole series of physical changes but that's a different issue.)
Coffee dissolving, water boiling and chocolate melting are reversible physical transformations whereas wood burning is a chemical combustive transformation.
melting chocolate is a good name. it depends if you are talking about what it is called after melting or while it is melting.
Changing a chocolate from soild to liquid requires the absroption of energy.
Melting chocolate is a physical reaction because it does not change the chemical composition of the chocolate. It only involves the change in state from a solid to a liquid due to the application of heat.
Lindor is a type of chocolate made by Lindt. Lindor was introduced by Lindt in 1949 and is a special kind of chocolate with a smooth, melting filling.
Chemical Change!Because when chocolate start out as just chocolate but when it melts it becomes a chemical because its just something to drink like water,Water is a chemical beause its just something to drink,but you don't actuly drink chocolate,it just becomes a chemical because it melts in to a liquid and all liquids are just becomes a solid,so Chocolate is a chemical when it melts because its just like water but chocolate isn't water its just like water because it melts into a chemical!
