Question

what is a melting? ​

Answer 1

Answer:

Melting is the process of changing the phase of a substance from solid to liquid by adding heat to the system. Examples of melting are the following: ... Ice melts to liquid water at temperatures above 0 °C.Melting point is the temperature at which a given solid will melt. At the melting point the solid and liquid phase exist in equilibrium. Eg. Melting point of ice at a pressure of one atmosphere is 0°C (32°F) For iron it is 1,535°C (2,795°F)The melting point is an important physical property of a compound. The melting point can be used to identify a substance and as an indication of its purity. The melting point of solid is defined as the temperature at which the solid exists in equilibrium with its liquid under an external pressure of one atmosphere.As the atomic number of elements increases, the melting point increases because there are more electrons around the nucleus, which creates a stronger negatively-charged force. With stronger forces, the melting point rises. 3. Non-metals usually have low melting points.. Butter melts in a frying pan. Candle wax melts in the heat of the candle's flame.Examples include:

Melting Ice to liquid water.

Melting of steel (requires very high temperature)

Melting of mercury and Gallium (both are liquid at room temperature)

Melting of butter.

Melting of candle.

Most things do not melt, but undergo chemical change on heating, e.g. people, plants, animals, concrete, books. Things that do melt are the exception. ... However you can make CO2 into a liquid under pressure (as it is within a gas cylinder) and you can freeze the liquid to solid, then melt the solid to liquid).

The process in which a solid substance changes into a liquid on heating, is called melting...
