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 ...
It is a physical constant which provides the computation of the amount of energy to the random thermal motions of the particles making up the substance. A great Austrian physicist Ludwig Boltzmann said: If the temperature of the gas molecules is high, then the average kinetic energy of molecules...
The article discusses the kinetic gas equation derivation based on the kinetic gas theory postulates. The formula of the rms velocity of gas molecules is also given here.
To derive theexpression for drift-velocity, its relation with the mobility of electrons and the effect of applied external electric field have to be known. Mobility of an electron is defined as it’s Drift Velocity for a unit electric field. The electric field is proportional to the current. ...
The dotted curve indicates the real variation of atmospheric temperature with altitude. The barometric formula can be obtained from the law of velocity and coordinate distribution of the molecules of an ideal gas in a potential force field. Two conditions—constancy of gas temperature and uniformity ...
In the equation below, M is mass, N is moles, v is velocity, and A and B refer to gasses of species A and species B. The abbreviation rms is short for root mean squared, a method of calculating average velocity. {eq}KE = \frac{1}{2} \frac{M_A}{N_A} v^2_{rms,A} = \...
The viscosity of liquids is different from gas. When dealing with this less contained state of matter, a higher temperature actually causes them to "thicken," and their viscosity increases with temperature. This is because for gasses at low temperatures, the molecules rarely collide or interact wi...
This corresponds to an atmospheric half-life of about 6.8 and 3.4 days for cis- and trans-isomers, respectively, at an atmospheric concentration of 7X10+11 ozone molecules per cu cm(2). Cinnamaldehyde is not expected to undergo hydrolysis in the environment due to the lack of functional ...
Contaminated clothing should not be taken home at the end of shift, but should remain at employee's place of work for cleaning.|ACCIDENTAL RELEASE MEASURES: Personal precautions, protective equipment and emergency procedures: Use personal protective equipment. Avoid breathing vapors, mist or gas. ...
The kinetic energy of a single molecule is given as half of the product of its mass and velocity squared (K.E = mv2/2). Since temperature is defined as the measure of the average translational kinetic energy of the molecules, temperature and motion of molecules of a gas are propo...
