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.Continue Reading
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
The element Tungsten has the highest melting and boiling points of any known substance, melting at 6,192 degrees Fahrenheit and boiling at 10,031 degrees Fahrenheit. For this reason, Tungsten is used in many applications that require dealing with very high temperatures.Full Answer >
Sodium chloride has a high melting point because of the strong electrostatic attraction between its positive and negative ions; this requires more heat energy to overcome. All ionic compounds have high melting points for this reason.Full Answer >
Sugar does not have a fixed melting point. Instead, as sugar increases in temperature, its molecules began to decompose. While heating sugar does produce a more fluid product known as caramel, it does not retain its chemical identity, which is a key element in the melting process.Full Answer >
About reports the melting point of gold is 1,064.43 degrees Celsius. The melting point of a solid is the temperature at which it becomes a liquid. Gold's boiling point is 2,807 degrees Celsius.Full Answer >
