The average speed of a perfume vapor molecule at room temperature is about 300 m/s, but you find the speed at which the scent travels across the room is much less than that. Explain why this is os
Homework Answers
The speed at which the scent of a fragrance travels is much less than the speed of the individual molecules that make it up because of the many collisions among molecules. Although the molecular speed between collisions is great, the rate of migration in a particular direction through obstructing molecules is very much less.

The average speed of a nitrogen molecule in air is about 6.70 ✕ 102 m/s, and its mass is about 4.68 ✕ 10-26 kg. (a) If it takes 2.90 ✕ 10-13 s for a nitrogen molecule to hit a wall and rebound with the same speed but moving in an opposite direction (assumed to be the negative direction), what is the average acceleration of the molecule during this time interval? m/s2 (b) What average force does the molecule exert on...

Q6. (1) Using the measured speed of sound from longer pipe, estimate the temperature of the lab room, with uncertainty. The speed of sound is given by v 331 +0.6T (m/s), where T is the temperature in degrees Celsius. Does this find the lab room to be significantly warmer or colder than room temperature (say, 20+20C)? Justify using your uncertainties. Also, does this result make sense? Does...

Carbon disulfide (CS2)(CS2) has a vapor pressure of 300 Torr300 Torr at room temperature (almost half of atmospheric pressure). A sample of CS2CS2 at a temperature of ?=20.6∘CT=20.6∘C is contained in a vacuum chamber at a pressure of ?=200 TorrP=200 Torr in a research lab. The diameter of the CS2CS2 molecules is ?=2.00×10−10 m.d=2.00×10−10 m. The atomic mass of carbon is 12.0 g/mol12.0 g/mol and sulfur is 32.1 g/mol.32.1 g/mol. Assuming that carbon disulfide has only translational degrees of freedom...

The speed of sound through air at room temperature and standard pressure is about 343 m/s. One cue the human hearing system uses to localize sound is the slight difference in the arrival times at the two ears of the sound emanating from a source. Ears are spaced about 20cm apart. Consider a person facing the positive x-direction and a source located 5 m away at an angle of 45° below the positive x-direction. What is the difference in arrival...
