The viscosity equation further presupposes that there is only one type of gas molecules, and that the gas molecules are perfect elastic and hard core particles of spherical shape. This assumption of elastic, hard core spherical molecules, like billiard balls, implies that the collision cross section of one molecule can be estimated by σ = π ...
For gases, departure from 3 R per mole of atoms is generally due to two factors: (1) failure of the higher quantum-energy-spaced vibration modes in gas molecules to be excited at room temperature, and (2) loss of potential energy degree of freedom for small gas molecules, simply because most of their atoms are not bonded maximally in space to ...
Avogadro's law states that "equal volumes of all gases, at the same temperature and pressure, have the same number of molecules." [1] For a given mass of an ideal gas, the volume and amount (moles) of the gas are directly proportional if the temperature and pressure are constant.
Equipartition therefore predicts that the total energy of an ideal gas of N particles is 3 / 2 N k B T. It follows that the heat capacity of the gas is 3 / 2 N k B and hence, in particular, the heat capacity of a mole of such gas particles is 3 / 2 N A k B = 3 / 2 R, where N A is the Avogadro constant and R is ...
The molar gas constant (also known as the gas constant, universal gas constant, or ideal gas constant) is denoted by the symbol R or R. It is the molar equivalent to the Boltzmann constant , expressed in units of energy per temperature increment per amount of substance , rather than energy per temperature increment per particle .
Since Gatorade is so effective at delivering glucose to muscles quickly, Brown says that the best time to drink Gatorade is when you need a quick energy and hydration boost, but you don’t have a ...
Kerr saw it (as did a number of players) and frantically started shouting and motioning to the referees, calling for a technical foul, which is the punishment when a player tries to take a timeout ...
Historically, the mole was defined as the amount of substance in 12 grams of the carbon-12 isotope.As a consequence, the mass of one mole of a chemical compound, in grams, is numerically equal (for all practical purposes) to the mass of one molecule or formula unit of the compound, in daltons, and the molar mass of an isotope in grams per mole is approximately equal to the mass number ...
