Question

As the temperature is raised from $20^{\circ}C$ to $40^{\circ}C$, the average kinetic energy of neon atoms changes by a factor of which of the following?

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

Answer 1

Answer: (C)

$\frac{313}{293}$

Answer 2

$\frac{E_{1}}{E_{2}} = \frac{T_{1}}{T_{2}}$ $\frac{E_{1}}{E_{2}} = \frac{293}{313}$ $\because$ factor $= \frac{313}{293}$
