Answer 2

Hello dear,

● Answer -

T' = 4800 K

● Explaintion -

According to kinetic theory of gases, RMS velocity of a gas is given by -

vrms = √(3RT/M)

vrms ∝ √T

Now we have v' = 4v,

v' / v = √T' / √T

4v / v = √T' / √300

T' = 16 × 300

T' = 4800 K

Therefore, RMS velocity will be 4 times at the temperature of 4800 K.

Hope this helped you.
