Which Postulate Of The Kinetic Molecular Theory Breaks Down Under Conditions Of Low Temperature?

Which postulate of the kinetic molecular theory breaks down under conditions of low temperature? Explain. Answer: The lower the temperature, the lower the pressure than the ideal gas law predicts. Explanation At lower temperatures, the molecules have reduced kinetic energy. Lower kinetic energy reduces successful collisions and thus reduces reactivity and the number of interactions. …

Write the Equation in Spherical Coordinates

Write the equation in spherical coordinates. x^2−2x+y^2+z^2=0 Answer:  Recall that in spherical coordinates x = psin 0 cosO and that x^2+y^2+z^2=p^2. By using this we obtain the equation: p^2 – 2psin 0 cosO = 0

When A Sound Wave Passes From Air Into Water, Do You Expect The Frequency Or Wavelength To Change?

When sound travels from air into water, does the frequency of the wave change? The speed? The wavelength? Explain your reasoning. Explanation Know the equation: wavelength = v/f. When sound travels from air into water frequency doesn’t change because it’s directly proportional to the source. Speed changes, because it is directly proportional to medium, and …
