The average speed of an ideal gas molecule at `27^(@)C` is `0.3 m, sec^(-1)`. The average speed at `927^(@)C`

Explanation

`v_1 = sqrt((8RT)/(piM))`
`V_(1) = 0.3 =sqrt((8 xx R xx 300)/(pixx M))`
`v_(2) = sqrt((8R xx 1200)/(piM))`
`v_2//0.3 = sqrt((8R xx 1200)/(piM) ) xx sqrt((pi M)/(8R xx 300)) = sqrt(1200/300)`
`v_2 =0.6 ms^-1`
