MCQ
An ideal gas undergoes four different processes from thesame initial state $($Fig.$)$. Four processes are adiabatic, isothermal, isobaric and isochoric. Out of $1, 2, 3$ and $4$ whichone is adiabatic.
  • A
    $4$
  • B
    $3$
  • $2$
  • D
    $1$

Answer

Correct option: C.
$2$
$4$ is isobaric process, $1$ is isochoric. out of $3$ and $2, 3$ has the smaller slope $($magnitude$)$ hence is isothermal. Remaining process $2$ is adiabatic.

This question has Statement $-1$ and Statement $-2$. Of the four choices given after the statements, choose the one that best describes the two statements.

If two springs $S_1$ and $S_2$ of force constants $k_1$ and $k_2$, respectively, are stretched by the same force, it is found that more work is done on spring $S_1$ than on spring $S_2$.

Statement $-1$: If stretched by the same amount, work done on $S_1$, will be more than that on $S_2$

Statement $-2$ : $k_1 < k_2$.
