Sort the following liquids in the increased order of the viscosity.

Q. When temperature is increased, then which of the following is true?
a) Viscosity of the gas increases.
b) Viscosity of the gas decreases.
c) Viscosity of the liquid decreases.
d) Viscosity of the liquid increases.

Q. Viscosity of a liquid arises due to strong intermolecular forces existing between the molecules. The stronger the intermolecular forces, the greater is the viscosity. Name the intermolecular forces existing in the following liquids and arrange them in the increasing order of their viscosities. Also give reason for the assigned order in one line.

Water, hexane $\left(C{H}_{3}C{H}_{2}C{H}_{2}C{H}_{2}C{H}_{2}C{H}_3\right)$, glycerine $\left(C{H}_{2}OHCH\right(OH\left)C{H}_{2}OH\right)$.

Q. Sort the following in increasing order.
