Answer:
Boiling Water
Explanation:
Boiling water is a physical change because the gaseous water produced is chemically identical to the liquid water i.e both of them have the same molecular structure of the water
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
Electrically neutral molecules formed by covalent bonds between atoms that have the same or similar electronegativity are called Nonpolar.
Polar on the other hand is a term that describe a molecule with an asymmetrical distribution of charges. such a molecule has a negative pole and a positive pole.
