A cylinder is filled with 10.0 L of gas and a piston is put into it. The initial pressure of the gas is measured to be 90.1 kPa .The piston is now pulled up, expanding the gas, until the gas has a final volume of 49.0 L. Calculate the final pressure of the gas. Round your answer to 3 significant digits.

18.4 kPa

Explanation:

Step 1: Given data

Step 2: Calculate the final pressure of the gas

If we assume the gas behaves as an ideal gas, we can calculate its final volume using Boyle's law.

P₁ × V₁ = P₂ × V₂

P₂ = P₁ × V₁/V₂

P₂ = 90.1 kPa × 10.0 L/49.0 L

P₂ = 18.4 kPa

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
