વાયુનું દબાણ $0.4\%$ વધારવાથી તાપમાન $1°C$, વધે છે.તો વાયુનું શરૂઆતનું તાપમાન

A

$250\,K$

B

$250\,°C$

C

$2500\, K$

D

$25°C$

Solution

${P_1} = P$, $T1 = T$ ,

${P_2} = P + $ $(0.4\%\, of\,\, P) = P + \frac{{0.4}}{{100}}P = P + \frac{P}{{250}}$

${T_2} = T + 1$

$\frac{{{P_1}}}{{{P_2}}} = \frac{{{T_1}}}{{{T_2}}}$

==> $\frac{P}{{P + \frac{P}{{250}}}} = \frac{T}{{T + 1}}$

$T = 250\, K$.
