How are characteristic properties of a given substance different from its other properties and chemical properties?
lesya [120]

Answer : The characteristic properties of a substance always remains the same irrespective of the sample being observed is large or small.

Few examples of characteristic properties of any substances includes freezing or melting point, boiling or condensing point, density, viscosity and solubility. They are specific for specific substances and which makes them easily recognizable.

Whereas chemical properties are specific for one substance which chemically transformed into another substances.

Will these changes increase, decrease, or have no effect on the mean free path of the molecules in a gas sample?
lisabon 2012 [21]
According to the kinetic theory, the mean free path is the average distance a single atom or molecule of an element or compound travels with respect with the other atoms during a collision. The greater the mean free path, the more ideal the behavior of a gas molecule is because intermolecular forces are minimum. To understand which factors affect the mean free path, the equation is written below.

l = μ/P * √(πkT/2m), where
l is the mean free path
μ is the viscosity of the fluid
P is the pressure
k is the Boltzmann's constant
T is the absolute temperature
m is the molar mass

So, here are the general effects of the factors on the mean free path:

Mean free path increases when:
1. The fluid is viscous (↑μ)
2. At low pressures (↓P)
3. At high temperatures (↑T)
4. Very light masses (↓m)

The opposite is also true for when the mean free path decreases. Factors that are not found here have little or no effect.
