Solution

The correct option is D lip of the tube is moved to level II
On increasing the pressure the solubility of a gas in liquid increases and on increasing the temperature solubility decreases,

So, on the moving lip of the tube to level II, the pressure increases and hence, solubility also increases.

Q. In order to carry out the decomposition reaction of water, a student passes electric current from a battery through water containing a few drops of dilute sulphuric acid. In this process, two volume of gas X are collected in a test-tube inverted over cathode (negative electrode) whereas one volume of gas Y is collected in the test-tube inverted over anode (positive electrode).
