19. A sample of an ideal gas is in a tank of constant volume. The sample absorbs heat energy so that its temperature changes from 300 K to 600 K . If `vl` is the average speed of the gas molecules before the absorption of heat and `v2` is their average speed after the absorption of heat, what is the ratio `v2/v1` ?
(A) 4
(B) 2
(C) `2`
(D) `1/2`
