MCQ
Equal mass of three liquids are kept in three identical cylindrical vessels $A, B$ and $C$. The densities are $P_A, P_B, P_C$ with $P_A$   
  • A
    Maximum in vessel $A$.
  • B
    Maximum in vessel $B$.
  • C
    Maximum in vessel $C$.
  • Equal in all the vessels.

Answer

Correct option: D.
Equal in all the vessels.
The force on the base is given by:
$F = hpg \times A$
$\Rightarrow F = (hpg)g$
$\Rightarrow F = ($volume $\times$ density$) \times g$
$\Rightarrow F = mg$
In the question, the masses are equal.
So, the force on the base is the same in all cases.

Graphs below show the entropy versus energy $U$ of two systems $1$ and $2$ at constant volume. The initial energies of the systems are indicated by $U_{1, i}$ and $U_{2, i}$, respectively. Graphs are drawn to the same scale. The systems are then brought into thermal contact with each other. Assume that, at all times the combined energy of the two systems remains constant. Choose the most appropriate option indicating the energies of the two systems and the total entropy after they achieve the equilibrium.
