Question

By what ratio the average velocity of the molecule in gas change when the temperature is raised from ${50}^{\circ }C\text{to}{200}^{\circ }C$?

• A. $1.21/1$
• B. $1.46/1$
• C. $1.14/1$
• D. $4/1$

Answer 1

The correct option is A $1.21/1$

Absolute temp $=200+273$

$\therefore$ acc to formula $\sqrt{\frac{(200+273)}{(50+273)}}$

$=\sqrt{\frac{473}{323}}=\sqrt{\frac{1.46}{1}}=\frac{1.201}{1}$

$1.21:1=\left(A\right)$ option is correct
