Calculate the Root Mean Square (rms) Speed of oxygen gas at room temperature The formula for the rms speed of a gas requires the appropriate R gas constant (8.314 J/mol-K) and requires the molar mass (MW) be in kg/mol instead of g/mol. For fun, the speed calculated in m/s is converted to mi/hr.

Multiphysics Cyclopedia (1) so. (2) A typical diffusion coefficient for a molecule in the gas phase is in the range of 10-6 to 10-5 m2/s. By contrast, diffusion for molecules dissolved in liquids is far slower. In an aqueous (water) solution, typical diffusion coefficients are in the range of 10-10 to 10-9 m2/s.

All-1B-allanswer - CHAPTER 14 CHEMICAL KINETICS PRACTICE... In many cases, the amount of gas evolved by a reaction is of interest. Since gases have such small densities, it is usually not practical to collect the gas and find its mass. For gases that are not particularly soluble in water, it is possible to collect the evolved gas by displacement of water from a container.his equation can be used to calculate the pressure of the gas collected. Once the pressure of the collected gas is known, the number of moles of gas can be calculated using the ideal gas law: PV= nRT. Where: 1  P = Pressure of the gas. 2  V = Volume of water displaced. 3  n = number of moles of gas. 4  R = the ideal gas constant.

Kinetic Molecular Theory 1 Collisions of molecules with each other or the walls of the container do not decrease the energy of the system. 2  The molecules of a gas are in constant and random motion. 3  The temperature of a gas depends on its average kinetic energy avg(1/2mv 2) = 3/2kT. 4  In other words, the energy of an ideal gas is entirely kinetic.

Difference Between Cardiac and Skeletal Muscle Another difference is that the cardiac muscles are short in comparison to skeletal muscles. The skeletal muscles are attached to the bone through tendons. The skeletal muscles also contain myoblasts, which form the fibers in the muscles. The cardiac muscles are seen in the myocardium of the heart.

- When a volume of gas is enclosed in a container, the molecules/atoms forming the gas move about within the container, colliding elastically with each other, and the sides of the container, creating pressure against the sides of the container.

- The gas's internal energy is almost all kinetic, the sum of the kinetic energies of random motion of the molecules. (3) The pressure the gas exerts on its container walls, stationary or moving, is not any sort of energy. Its unit of pressure are N m-2; those of energy are N m. (4) When the container expands against opposing forces, for example if the gas is in a cylinder fitted with a piston which moves outwards, pushing something, then the gas does work (integral pdV).

Ideal Gas Law But there is also a statistical element in the determination of the average kinetic energy of those molecules. The temperature is taken to be proportional to this average kinetic energy; this invokes the idea of kinetic temperature. One mole of an ideal gas at STP occupies 22.4 liters.

What is a Genset? A genset, or distributed generator system, is an electrical generator, such as a solar panel, gasoline powered generator, or windmill, located in proximity to the end-user rather than in a central location, like those utilized by commercial power providers.ometimes, it is necessary to isolate a section of the grid for work and it is difficult to ensure that power is off to that section if distributed generation is occurring. Distributed generation may also affect the overall quality of power in the grid, making it difficult for a commercial utility to control.
