$27°C$ તાપમાને રહેલા $22\ gm$ $C{O_2}$ માં $37°C.$ તાપમાને રહેલા $16\ gm$ ${O_2}$ નાખતા અંતિમ તાપમાન .......... $^oC$ થાય?

A

$27$

B

$30.5$

C

$32$

D

$37$

Solution

${\mu _1}{C_{{v_1}}}\Delta {T_1} = {\mu _2}{C_{{v_2}}}\Delta {T_2}$

$\Rightarrow$  $\frac{{22}}{{44}} \times 3R \times (T – 27) = \frac{{16}}{{32}} \times \frac{{5R}}{2}(37 – T)$

$\Rightarrow$  $ T = 31.5°C ≈ 32°C$
