Question

The root mean square of a certain gas at 27° C is 3×10000 cm /sec. The temperature at which the velocity will be 6× 10000cm/sec is

Answer 1

Explanation:

RMS velocity is proportional to square root of temperature.

if the RMS velocity is to be doubled then temperature must be increased by 4 times.

therefore required temperature will be

4*300 ° k = 1200 k

or 1200 = 927 ℃
