Answer: C
creativity
Explanation:

known theories.
Answer:
1 to 696
The expansion ratio of liquefied and cryogenic from the boiling point to ambient is: nitrogen 1 to 696. liquid helium 1 to 757. argon 1 to 847.
Explanation:
Diamond and graphite are made of carbon. So is most of charcoal.
Explanation:
<u>Periodic table is the tabular display of elements that are arranged by the increasing atomic number.
</u>
Structure of the periodic table shows various periodic trends.
<u>Significance:
</u>
The periodic table is very important because it gives an organized way to provide lots of information about the elements and how they can be related to one another. The table gives a systematic approach to study the elements and their properties. The table can also be used to predict the properties of the elements which have not been discovered yet.
Answer:
<h2>D. Nonpolar molecules</h2>
Explanation:
The non-polar molecules are held in place by very weak van der Waals forces, hence making it to have the least melting and boiling point.
The melting points of substances is the point at which it changes from solid to liquid, it can be very difficult to ascertain that why mostly the melting point is given as a range of values.
