Asample of an ideal gas is in a tank of constant volume. the sample absorbs heat energy so that its temperature changes from 302 k to 604 k. if v1 is the average speed of the gas molecules before the absorption of heat and v2 their average speed after the absorption of heat, what is the ratio v2/v1?

1.v2/v1 = 2.
2.v2/v1 = 4
3.v2/v1 = √2
4.v2/v1 = 2
5.v2/v1 =1/2
