Question: 22 gm of CO<sub>2</sub> at 27<sup>0</sup>C is mixed with 17 gm of O<sub>2</sub> at 37<sup>0</sup>C. ...

22 gm of CO2 at 270C is mixed with 17 gm of O2 at 370C. If both gases are considered as ideal kinetic theory gases then the temperature of the mixture is-

A

320C

B

270C

C

370C

D

30.50C

Answer

320C

Explanation

Solution

Tmix = n1T1+n2T2n1+n2\frac{n_{1}T_{1} + n_{2}T_{2}}{n_{1} + n_{2}} \simeq 320C
