Considering the relationship between volume and temperature, a gas under constant pressure can only have its volume reduced as a result of a decrease in its temperature.
According to Charles law, at constant pressure, the volume of a gas is directly proportional to its absolute temperature. Thus:
V1/T1 = V2/T2 where V1 = intial volume, V2 = final volume, T1 = initial temperature, and T2 = final temperature.
In this case, T1 = 59.0, V1 = 30.57, and V2 = 21.14
T2 = 21.14 x 59/30.57
= 20.05 K
It can be seen that the temperature of the gas has reduced from 59.0 K to 20.05K.

Single displacement is the type of chemical reaction
The pH scale was given by Sorensen to quanitatively define strength of an acid and base
the pH scale extends from 0 to 14
For acids
The pH should be less than 7 [always]
For base
The pH should be more than 7 [always]
The pH seven is of neutral solution
pH = -log[H+]
Thus lower the pH higher the concentration of hydronium ion or protons produced by an acid
thus for the given pH scale interval [0-3] it represents strong acid [Which will give high concentration of protons on dissociation]
