penyelesaian
T = 27 + 273= 300 K
V = akar(3RT/M)
= akar(3 x 8315 x300 / 32)
=483.59 m/s
T = 27⁰C = 300⁰K
R = 8,314
V rms = .................?
Penyelesaian :
V rms = √3RT / M
V rms = √(3 • 8,314 • 300) / 0,032
V rms = √7482,6 / 0,032
V rms = √233831,25
V rms = 483 m/s
Jadi, klaju efektifnya adalah 483 m/s (Jawaban A)
