The melting of ice is a physical change. A physical change involves states of matter and energy. The melting of ice is a phase change, which is a type of physical change.Know More
Other examples of physical change include sublimating dry ice, boiling water, crushing an aluminum can or breaking a glass bottle. While matter takes a different form during a physical change, no new substance is created.
On the other hand, in a chemical change, a new product is created following a chemical reaction. Examples of chemical changes include cooking an egg, using a chemical battery or burning a candle.Learn more about States of Matter
Baking a cake is a chemical change, not a physical change. A physical change does not produce a new substance, as it only involves a change in state, like butter melting or water freezing. A finished cake, on the other hand, is entirely different from the ingredients that were used to make it.Full Answer >
Boiling water is a physical change, as it rearranges molecules but does not affect the internal structures. Boiling water forces the water molecules away from each other as the liquid changes to vapor. In a chemical change, new chemical substances are created or formed.Full Answer >
Solids that are held together by covalent bonds have the highest melting points because the molecules are firmly held together in a crystal lattice. This property makes such solids poor electrical conductors since the molecules cannot move. The metallic solid tungsten has the highest melting point among the elements.Full Answer >
Tungsten, element 74, has the highest melting point of all of the elements on the periodic table. Its melting point is approximately 3,695 Kelvin, or 3,422 degrees Celsius.Full Answer >
