Is melting a process or reaction?
Melting is a physical process in which the transfer of phase from solid to liquid takes place. Chemical changes involve either absorption of heat or the release of heat. So melting is an endothermic process because needs to apply external heat to the solid substance in order to make it melt.
The melting of ice absorbs heat, so it is an example of an Endothermic reaction.
The melting of ice is an example of an endothermic reaction.
melting, change of a solid into a liquid when heat is applied. In a pure crystalline solid, this process occurs at a fixed temperature called the melting point; an impure solid generally melts over a range of temperatures below the melting point of the principal component.
Ice melting is not a chemical reaction because when an ice is melting there is no chemical change happening upon the ice. The water molecules are still the same, they are still water molecules.
Atoms may bond, and then those bonds may break to form new molecules. The melting of ice is a physical change when it occurs naturally. But when you speed up the process by using a reactant, such as salt, it becomes a chemical reaction.
Ice melting is not a chemical reaction because when an ice is melting there is no chemical change happening upon the ice. The water molecules are still the same, they are still water molecules.
A physical change occurs whenever only the physical structure of a substance changes. The most common physical changes are changes in states of matter, such as the melting process and freezing process. Melting is the process of turning a solid into a liquid.
Melting of ice cream is a physical change. Liquid ice-cream solidifies again on freezing without change in chemical properties.
Melting is the process of changing a solid substance into a liquid. During the melting process, heat is added to a substance, increasing the amount of energy in the particles present in the substance.
Is water melting a chemical reaction?
No chemical changes took place when you melted the ice. The water molecules are still water molecules. So melting of ice into water is a physical change.
