Distinguish between average seed and r.m.s. speed. If the three molecules have speeds v1,v2,v3, what will be their average aped and r.m.s. speed? |
|
Answer» Average speed is the arithmetic mean of the speeds of the molecules ∴ Average speed = \(\frac{v_1+v_2+v_3}{3}\) r.m.s. speed is the root mean square speed and is defined as the square root of the mean of the squares of random speeds of the individual molecules. vrms = \(\sqrt\frac{v_1^2+v_2^2+v_3^2}{3}\) |
