The vapour of a pure chemical substance depends on the level of a intermolecular forces, that substance's structure, and the temperature.
<h3>What are instances of intermolecular forces?</h3>
Between molecules, intermolecular forces are at work. In contrast, molecules themselves exert intramolecular pressures. In comparison to intramolecular forces, intermolecular forces are weaker. The Weaker intermolecular forces, dipole-dipole interaction, ion-dipole communication, and van der Waals forces are a few examples of intermolecular forces.
<h3>What causes intermolecular forces?</h3>
Electrostatic in nature, forces between molecules result from the interaction of positive and negative charges entities. Forces between molecules are the total of both attracting and repulsive elements, similar to held together by covalent connections.

Answer:
They both come from the main idea, but the theory of continental drift states that the world was made up of a single large continent. The theory of plate tectonics state that the Earth's surface was broken into smaller pieces.

Data:
p = 1 atm
V = 10 m * 8 m * 5 m = 400 m^3 = 400,000 liter
To = 0 + 273.15K = 273.15K
Tf = 20 + 273.15K = 293.15K
No - Nf =?
2) Formula
pV = NRT => N = pV / (RT)
3) solution
No = pV / (RTo)
Nf = pV / (RTf)
=> No - Nf = [pv / R] [ 1 / To - 1 / Tf ]
=> No - Nf = [1atm*400,000liter / 0.0821 atm*liter/K*mol ] [ 1 / 273.15 - 1 / 293.15]
No - Nf = 1216.9 moles ≈ 1217 moles
Answer: 1217 moles
