Qn.44 :-  If mercury drop moves towards container, pressure in container-I increases.
For ideal gas, pressure increases if temperature increases or volume decreases.
 
Hence answer to the question :- (C)   I and IV
 
--------------------------------------------------------
 
Qn.(45) :-  if mercury is stationary, then pressure on both side is same. 
If temperature is same and pressure is also same for two containers of different volume containg same gas,
then number of moles of gases are proportional to volume. More number of moles means more mass.
 
Hence answer is :- (D) mass is proportional to container volume

The number of moles in an elemental sample is just the ratio of the mass m to atomic mass 4. n= A The number of protons N, in an elemental sample is Z (atomic number) times the number of moles of Avogadro's number NA N=ZnN P A Copper has an atomic mass of 63.5 g/mole and 29 protons per atom. If such an atom were neutral, then it would have as many protons as electrons. If you remove electrons from a neutral state, then you get a net positive charge. Given a 54 gram ball of copper with a net charge of 2.2 µC, what fraction of the copper's electrons have been removed?
