1.	The average velocity of an ideal gas molecule at27C is 0.3 m/s. The average velocity at 927°C willbe(1) 0.6 m/s(3) 0.9 m/s(2) 0.3 m/s(4) 3.0 m/s
Answer» 27°C = 300 K927°C = 1200 K Average velocity ∝ sqrt(Absolute Temperature) v1 / v2 = sqrt(T1 / T2)0.3 / v = sqrt(300 / 1200)0.3 / v = 1 / 2v = 0.6 m/s Average velocity at 927°C is 0.6 m/s

The average velocity of an ideal gas molecule at27C is 0.3 m/s. The average velocity at 927°C willbe(1) 0.6 m/s(3) 0.9 m/s(2) 0.3 m/s(4) 3.0 m/s

Answer»

27°C = 300 K927°C = 1200 K

Average velocity ∝ sqrt(Absolute Temperature)

v1 / v2 = sqrt(T1 / T2)0.3 / v = sqrt(300 / 1200)0.3 / v = 1 / 2v = 0.6 m/s

Average velocity at 927°C is 0.6 m/s
