Question

When a certain mass of an ideal gas is adiabatically compressed so that its volume is reduced to 1/32
times, its absolute temperature is increased 4 times. The number of atoms in a molecule (atomicity)
of the gas is
(A) 3
(B) 4
(C)2
(D) 1​

Answer 1

Answer:

option(d)

Explanationbecause atomicity remain same

Answer 2

Answer is Option C

Explanation:

Adiabatic Process - The Process That happens with Neither Heat Transfer and nor mass transfer, but its only work transfer.

$T(V)^{r-1}$ = constant

$\frac {T_1}{T_2} = (\frac {V_1}{V_2})^{r-1}$

$4 = (32)^{r-1}$

$r = \frac {7}{5}$

Hence, Its a Diatomic gas.
