Explain how the size of hydrocarobon molecules affects the strength of intermolecular forces?

The longer the hydrocarbon chain, the stronger the intermolecular forces. This leads to higher boiling point, and these chains are likely to be less useful.

Explain why oil does not dissolve in water.?
The main intermolecular forces between water molecules are hydrogen bonds which are pretty strong as far as intermolecular forces go. Between hydrocarbon chains (oil) the main intermolecular force are London force which are weaker. For two liquids to be miscible the intermolecular forces between them have to be similar in strength or they won't dissolve. Water and oil have different strengths of intermolecular bonds so don't mix.
How atom and molecules are important to cell processes explain?

How do you explain the of gases?
Gases are substances with very weak bonds between molecules.
Explain what determines the viscosity of a liquid?
the shape and size of the molecules that the fluid consists of, if they are big, wavy molecules then the liquid will be viscous because the molecules struggle to move over each other.
Explain what is the difference between real gas molecules and ideal gas molecules by kinetic theory?
In an ideal gas, molecules don't take up space, and don't have long-range interactions.

Why symmetry model can only explain positive homotropic cooperativity?
Homotropic molecules have chemically identical H's. As in the molecule can be cut in half and the hydrogens are all of the same molecular strength.
What intermolecular forces explain why water is a liquid at room temperature?
You think probable to hydrogen bonds.
how do you explain what polar molecules are?
Water molecules are polar molecules. Both of the bonds inside the molecule are polar bonds.
How do you explain the solubility of compounds?
List all the intermolecular forces between solutes2) List all the forces between solvents3) List all the intermolecular forces between solvent and solute4) State the energy comparisons.
The temperature of a sample of an unknown gas goes from 100 K to 5 K and the volume and number of moles remains constant would you expect the sample of gas to behave more or less ideally and explain?
Generally, the lower the temperature, the less ideally a gas behaves. The main reason for this is that in an ideal gas, intermolecular forces are ignored. The slower the molecules go, the bigger the influence of intermolecular forces, the less ideal the gas.
Do polar molecules conduct energy as well as ionic molecules explain?
no, because there are no ions present.
