Answer:
Step-by-step explanation:
The process of melting a chocolate bar involves the input of heat energy. The chocolate receives the energy from an outside heat source, like a stove or microwave.
The thermal energy used in the melting process raises the temperature of the chocolate. The cocoa butter and other ingredients in chocolate start to melt as the temperature rises, changing the substance from a solid to a liquid.
The intermolecular connections within the chocolate's structure are mostly broken by the energy that is added to the chocolate. The molecules of cocoa butter are held together by these bonds to create a solid.
