States of Matter Notes Class 11 Chemistry Chapter 5

1. Change of condition.  It is fully influenced by intermolecular forces, molecular interaction energy and thermal energy.

 2. Measurable properties of gases.  P, V, T, n, viscosity, specific heat are some measurable properties.

 3. Gas laws.  The ratio of the variable quantity b / w and any two variables (V, n, P, T) when the other two are stable.

 4. Boyle's Law.  The pressure of the solid gas mixture varies with the volume P-1 / V (n, T continued).  In the opposite case of P1V1 = 2V 2.

 5. Charlie's Law.  At a constant P, the volume of a solid gas differs directly from the absolute temperature.

 6. Gay-Lucy's Law.  At a constant V, the pressure of a large amount of gas depends directly on the absolute temperature.

 7. Ideal gas equation.  B / w P, V և T ratios according to gas law PV = nRT.

 8. Avogadro's Law.  In T և P it is said that the volume of gasoline is directly related to the amount of gas.  V α n (P, T stable)

 9. Dalton's law of partial persuasion.  The pressure generated by the mixture of non-reactive gases is equal to the sum of their partial stability pressures (V, T) P = P1 + P2 + P3 + ……….  (T, V, constant)

 10. Kinetic molecular theory.

 a.  Gases consist of a large number of identical particles (atoms or molecules) that are so small that the actual volume of the molecules is negligibly small compared to the empty space between them.

 b.  Under normal temperatures, under the pressure of the gas particles, no power is involved

 c.  Gas particles are always in constant and random motion

 d.  Pressure marking is done by the gas due to the collision of particles on the walls of the containers

 e.  Collisions of gas molecules are perfectly elastic

 f.  Especially at a specific time, different gas particles have different velocities and consequently different kinetic energy

 c.  The average kinetic energy of gas molecules is directly proportional to the absolute temperature

 11. Actual gases.  Gases are added that deviate from the ideal behavior by the force of high pressure և low temperature b / c force b / s molecules.

 12. Compression factor (Z).  It determines the degree of deviation of the actual gases from the ideal gas behavior

  Z = 1 for ideal gas formula, Z <1, Z> 1 for non-terrestrial gas

 Vandor Walls equations.  - a և b constants have positive values: typical of individual gas.  Van der Waals' equation of state approximates the ideal gas law

 14. Critical temperature.  (Tk) The temperature at which gas cannot be liquefied, what a high pressure it can be

 15. Critical pressure.  The minimum pressure required to liquefy gas at the critical temperature.

 16. Critical volume.  Determine the volume of 1 mole in Tc, pieces

 17. Frozen liquids.  Liquids cooled below freezing without freezing.

 18. Elastic collision.  Collisions in which there is no loss of K.E.  there is only energy transfer.

 19. Vapor pressure.  Contains the equilibrium pressure of a given liquid vapor in a container at a given temperature (T)

 20. At higher altitudes, b.p.  decrease in water b / c atmospheric pressure is less than one atmosphere.

 21. Surface tension (V).  This is the force acting on the length of each unit: on the vertical line.  (Nm-1) drops of liquid fall into the ball, the liquid in the capillary tube rises.

 22. Weave (h).  This is a resistance recommended for fluid flow

 23. The effect of T&P on viscosity.  It decreases with increasing T and increases with P.

 24. Low razor M.P.  & B.P.  Molecular fluids are due to the low energy content of molecular interactions.
