<span>Naphthalene has a higher melting point than biphenyl because naphthalene is a polar compound while biphenyl is a non-polar compound.</span> Studies show <span>that polar compounds have higher melting and boiling points than nonpolar compounds. It is because polar compounds have strong intermolecular forces.</span>

Answer: mole
A formula unit represents the simplest ratio of elements in a mole of an ionic compound.
Explanation:
The formula unit, also known as the empirical formula, gives the simplest whole number ratio of the components of the elements in a mole of an ionic compound.
Thus, the formula unit and the molecular formula of a compound can be the same.
For example: Glucose with C6H12O6 will have a formula unit of CH2O. Thus, the simplest ratio of carbon, hydrogen and oxygen in glucose is 1:2:1
For this question, suppose the pressure is remained constant, we can use the Charles law to find the answer.
Charles law:
V1/T1 = V2/T2
V1 and T1 are the initial volume and temperature (in K), and V2 and T2 are the final volume and temperature.
We just need to substitute in the numbers in order to find the new volume, V2.
1/5 = V2/10
5V2 = 10
V2 = 2
Therefore, the answer would be 2m3.
