Question

As the temperature is raised from 20oC to 40oC, the average kinetic energy of neon atoms changes by a factor :

• A. 2
• B. $\sqrt{\frac{313}{293}}$
• C. $\frac{313}{293}$
• D. $\frac{1}{2}$

Answer 1

Answer: (C)

$\frac{313}{293}$

Answer 2

K.E. = $\frac{3}{2}$RT

E1 =$\frac{3}{2}$ R 293 and E2 = $\frac{3}{2}$R 313 Ž E2

= $\frac{313}{293}$ × E1
