When a chocolate bar melts in the sun, it is a physical change. This is because the chocolate undergoes a phase change from a solid to a liquid without changing its chemical composition.
Physical, Since only the property of the chocolate didn't change, after it melted, it still is chocolate
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!
Physical Change
it is a chemical change
It is a physical change. There is no chemical reaction whatsoever.
It is a physical change.
When ice melts, it undergoes a physical change, not a chemical change. The molecules in the ice are still the same water molecules, but they are transitioning from a solid state to a liquid state.
No, melting is a physical change, not a chemical change. When the sun heats up and melts a crayon, it changes from a solid to a liquid state, but the chemical composition of the crayon remains the same.
Melting chocolate is a physical change, not a chemical reaction, so it is reversible. When chocolate melts, it changes from a solid to a liquid state due to the breaking of intermolecular forces. By cooling the melted chocolate, it can solidify back into a solid form without undergoing a chemical change.
When a chocolate bar melts in the sun, it is a physical change. This is because melting is a reversible process in which the chocolate changes from a solid to a liquid state due to the increase in temperature. No new substances are formed during this process, making it a physical change rather than a chemical change.
It is a physical reaction. Melting is a physical change because it does not change the chemical composition of the substance.
