The average molecular speed of

N_2

in a

4.0\,\text{L}

rigid container at

300\,\text{K}

u

. After the container is heated to

600\,\text{K}

, what is the new average speed

u'

of the molecules in terms of

u

? (Assume ideal behavior.) (a)

u' = 2u

(b)

u' = 1.71u

(c)

u' = \sqrt{2}\,u

(d)

u' = \dfrac{u}{\sqrt{2}}
