Answer:
Q1) a law stating that the volume of an ideal gas at constant pressure is directly proportional to the absolute temperature.
Q2) Open the image for Q2 ans.
Q3) The higher the value of a, the greater the attraction between molecules and the more easily the gas will compress. The b term represents the excluded volume of the gas or the volume occupied by the gas particles
Q4) The mass of dioxygen is 70.6 g.
The molar mass of dioxygen is 32 g/mol.
The number of moles of dioxygen
=
32 g/mol
70.6 g
= 2.21 mol
The mass of neon is 167.5 g.
The molar mass of neon is 20.2 g/mol.
The number of moles of neon
=
20.2 g/mol
167.5 g
= 8.29 mol
The total number of moles of neon and dioxygen = 2.21 + 8.29= 10.49
The mole fraction of neon =
10.49
8.29
= 0.789
Total pressure in the cylinder is 25 bar.
The partial pressure of neon = 0.789 × 25 bar= 19.7 bar
The partial pressure of dioxygen = 25 bar − 19.7 bar = 5.3 bar
Q5) Vapour pressure can be defined as pressure formed by the vapor of the liquid (or solid) over the surface of the liquid. This pressure is formed in a thermodynamic equilibrium state in a closed container at a certain temperature. Liquid’s evaporation rate is identified by the equilibrium vapor pressure. Vapour pressure increases with the temperature. The boiling point of the liquid is the point when the pressure exerted by surrounding equals to the pressure exerted by vapor. In this chapter, we will study more about the Vapour Pressure on liquids and its characteristics.
