Greatest average molecular speed
WebDec 17, 2024 · B. O_2 should be the correct answer for the reasoning given. Just as you stated, the gas with the lowest molar mass should have the highest speed, and O_2 has the lowest molar mass. This relationship is true since KE = 1/2mv^2, so if the temperature, also known as the average kinetic energy, is constant, mass is inversely related to velocity. WebYou then average all of these squared values and take the square root of that average. It's called a 'root mean square' and technically, it is a speed, not a velocity. ... A pure gas sample at 25 °C has an average molecular speed of 682 m/s. What is the identity of the gas? A) CH 4 B) H 2 C) HCl D) NO E) CO 2. Solution: v = (3RT) / M. 682 ...

WebThe compartment intensities, as percentage of sunlight in the open, were 22 per cent, 11 per cent and 6 per cent. Fans (Plate 3) operated at reduced speed gave a gentle air circulation through the compartments. To modify the quality of the radiation a water- filter was placed over some of the plants in the "50 per cent" area (Plate 4).
