The point at which a solid turns to a liquid is called the melting point. Farm Engines and How to Run Them James H. Stephenson With respect to the melting point, this variation is very remarkable.
This generally leads to low melting points for covalent solids, and high melting points for ionic solids. For example, the molecule carbon tetrachloride is a non-polar covalent molecule, CCl4. It's melting point is -23Â°C. By contrast, the ionic solid NaCl has a melting point of 800Â°C.
