The viscosity of a fluid is a measure of its resistance to deformation at a given rate. For liquids, it corresponds to the informal concept of "thickness": for example, syrup has a higher viscosity than water.
The pressure on the inside of the other side of the bottle is; 130kPa and this is by virtue of Pascal's Principle.
<h3>Pressure and Pascal's Principle</h3>
According to Pascal’s principle, otherwise called Pascal’s law, in fluid (gas or liquid) mechanics, the statement goes thus, In a fluid at rest in a closed container, a pressure change in one part is transmitted without loss to every portion of the fluid and to the walls of the container in which the fluid is contained.
On this note, it follows that the pressure is transmitted to the walls of the bottle.

We have to determine if the given compound is soluble or insoluble in water.
The given compound is copper (II) hydroxide, 
. According to the solubility rules the hydroxides of all metal ions are insoluble except that of ammonium and the alkali metal ions. So copper(II) hydroxide will be insoluble in water. In aqueous solution, copper (II) hydroxide would exist as a sparingly soluble compound in which the undissociated compound remains in equilibrium with the ions 
and 
. The equilibrium would remain mostly towards undissociated form.
Therefore, is insoluble in water.
