MCQ
The ratio of speed of sound in hydrogen gas to the speed of sound in oxygen gas at the same temperature is
  • $4:1$
  • B
    $1:2$
  • C
    $1:4$
  • D
    $1:1$

Answer

Correct option: A.
$4:1$
a
$C=\sqrt{\frac{\gamma R T}{M}}$

$C \propto \frac{1}{\sqrt{M}}$

$\frac{C_{H_2}}{C_{O_2}}=\sqrt{\frac{32}{2}}=4: 1$

A thermodynamic system is taken through cyclic process. The total work done in the process is $.........\,J$
Three different processes that can occur in an ideal monoatomic gas are shown in the $P$ vs $V$ diagram. The paths are labelled as $A \rightarrow B, A \rightarrow C$ and $A \rightarrow D .$ The change in internal energies during these process are taken as $E _{ AB }, E _{ AC }$ and $E _{ AD }$ and the work done as $W _{ AB }$ $W _{ AC }$ and $W _{ AD }$

The correct relation between these parameters are

Given below are two statements: One is labelled as Assertion $(A)$ and other is labelled as Reason $(R)$.

Assertion $(A)$ : Time period of oscillation of a liquid drop depends on surface tension $(S)$, if density of the liquid is $p$ and radius of the drop is $r$, then $T = k \sqrt{ pr ^{3} / s ^{3 / 2}}$ is dimensionally correct, where $K$ is dimensionless.

Reason $(R)$: Using dimensional analysis we get $R.H.S.$ having different dimension than that of time period.

In the light of above statements, choose the correct answer from the options given below.
