A) it is a solid because strong attractive forces prevent particles from moving.
Considering the definition of pOH and strong base, the pOH of the aqueous solution is 1.14
The pOH (or potential OH) is a measure of the basicity or alkalinity of a solution and indicates the concentration of ion hydroxide (OH-).
pOH is expressed as the logarithm of the concentration of OH⁻ ions, with the sign changed:
pOH= - log [OH⁻]
On the other hand, a strong base is that base that in an aqueous solution completely dissociates between the cation and OH-.
LiOH is a strong base, so the concentration of the hydroxide will be equal to the concentration of OH-. This is:
[LiOH]= [OH-]= 0.073 M
Replacing in the definition of pOH:
pOH= -log (0.073 M)
<u><em>pOH= 1.14 </em></u>
In summary, the pOH of the aqueous solution is 1.14

Answer:
If gas is cooled the particles will then stop moving about really fast and start to form a liquid. This is called condensation.. (i think) and it happens at the same amount of temperature as or when boiling. Evaporation is dependent on individual particles gaining enough energy to escape the surface of the liquid and become gas particles.
