A gas is at 20°C. To what temperature must it be raised to triple the rms speed of its molecules?

Can someone help me, I don’t understand this exercise. Its give another answer. Something like 6.6443×10^-27, too low. But the real answer is 2364oC

Formula for RMS velocity(C) is C=sq.rt(3RT/M)So, C directly proportional to T in kelvin(273+20=293)So, C1/C2=T1/T2C2=C1XT2/T13C1=C1XT2/T13=T2/T1T2=3XT1T2=3×293T2=2637k=(2637-273)=2364oC... Show More
