Question 5: Melting and Boiling Points (10 points)
sammy [17]

The position of the  solids in order from Lowest melting point to highest melting point are:

  • Non-polar molecular -  polar molecular -ionic solids - Covalent network.

<h3>What is meant by melting of point?</h3>

The melting point is a term that is defined as the point at which any given materials is altered from a solid to a liquid.

Note that the temperature at which solid is altered its said state to liquid at atmospheric pressure is seen as the melting point of that given  liquid.

Hence, The position of the  solids in order from Lowest melting point to highest melting point are:

  • Non-polar molecular -  polar molecular -ionic solids - Covalent network.
