what metal melts at 47 degrees celsius
When a pure crystalline substance is heated or cooled, it undergoes a transition between solid and liquid states. This transition, called melting, occurs at a precise point where most of the atoms gain enough thermal energy to break their bonds.
The melting temperature, more commonly known as the melting point, is a critical factor in a number of applications and manufacturing processes. It is important to know the melting point of a material so that you can determine which equipment will be safe for use with that material.
What Are The Chemical Elements With Low Melting Points?
The 118 elements in the periodic table are classified as either metals, semi-conductor(s), non-metal(s) or gases. In the periodic system, the elements are arranged by their atomic number (element #1) or oxidation state (element #3).
Those that have the lowest melting points are usually a combination of two or more base elements, often called an alloy. Tin/lead is a common example of this.
The enthalpy of formation or bond dissociation energy, and the melting point are related to each other. When a metal is in its crystalline solid state, the bonds that hold the atoms together are long and strong.
When a metal is heated, the bonds are broken and the atoms lose their order and density. As a result, the atoms expand to a greater volume and melt into a liquid state. This is also the reason why some alloys can be melted at a lower temperature than other metals.
