Unidades de Masa Atómica, o dalton (Da).
1. Loschmidt’s number also called as Loschmidt’s constant, n₀ is
the number of particles of an ideal gas in a given volume (m³). The unit is
m⁻³. At standard pressure (1 atm) and temperature (0 °C) the value of <span>Loschmidt’s number is
2.686 x 10</span>
²⁵ m⁻³.
2. Loschmidt’s number,n₀ can be expressed as,
n₀ =
where P is the pressure of the gas, K is the Boltzmann constant and T is the <span>thermodynamic temperature.
Since, k = R/NA (where R is the universal gas constant and NA is the Avogadro constant)
</span>n₀ =
n₀ =
Hence,
n₀ α NA
Nuclear is not a type of kinetic energy
Answer:
Both, the comb and the hair are comprised of atoms, which are, on their part, comprised of electrons ( negatively charged particles). When Sandra combs her hair, friction between comb and hair occurs. Since the electrons in hair are more loosely connected to each other than the ones in comb, during this friction some electrons from the hair will be transferred to the comb. Since electrons are negatively charged and the comb now has excess electrons that means that the comb becomes negative and the hair becomes positive ( because it loses negative charge). This friction is responsible for charging the hair and the comb. Finally, when the comb is placed near the hair, hair will move toward the comb since the opposite charges attract.
Answer:
Normal boiling point is the temperature at which a liquid boils at 1 atmosphere of pressure.
