The average velocity V of gas molecules is represented by the formula V=√ ( (3kt)m). The velocity is measured in meters per second, t is the temperature in Kelvin, and m is the molar mass of the gas in kilograms per mole. The variable k represents a value called the molar gas ...
题目The temperature of a gasis related to the average kinetc energyof its molecules by the formula:average K.E =张Twhere k=1.38*10^(-23) K-1 and T is the temperature in kelvin (K).The mass of an oxygen molecule is 8 times greater than the mass of a hydrogenmolecule. Two containe...
According to the Stefan-Boltzmann (SB) law, any physical object with a temperature above the absolute zero emits radiation with a total intensity that is proportional to the 4th power of the object’s absolute surface temperature. This implies that an object’s equilibrium surface temperature (T...
The probability density for speeds (magnitude of velocity) v of gas molecules proportional to f(v) = v^2 e - \frac{mv^2}{2kT}. Is the distribution function f(v) normalized? Find the average speed. (Hint: don't forget to normalize f(v) if it i...
