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.
Explain what determines the viscosity of a liquid?
Viscosity of a liquid is determined by the intermolecular forces between its molecules. Strong intermolecular forces lead to higher viscosity, as molecules resist sliding past each other. Temperature also affects viscosity, with higher temperatures decreasing viscosity by increasing molecular motion.
Explain what is the difference between real gas molecules and ideal gas molecules by kinetic theory?
Real gas molecules have volume and experience intermolecular forces, while ideal gas molecules are treated as point particles with negligible volume and no intermolecular forces. In real gases, molecules have varying speeds and collision effects due to their volume and interactions, while ideal gases follow the assumptions of the kinetic theory perfectly due to their simplified behavior.

Heat is removed from a gas and the substance becomes a liquld how can you explain this?
When heat is removed from a gas, its molecules lose energy and move more slowly, allowing them to come closer together. This results in the gas molecules transitioning to a liquid state due to the reduced energy and increased intermolecular forces. This process is known as condensation.

What is condensation explain on a molecular level?
Condensation is the process in which a gas changes to a liquid state. This occurs when the molecules in the gas lose energy, move closer together, and form intermolecular bonds. As a result, the molecules transition from a more disordered state (gas) to a more organized state (liquid).
What intermolecular forces explain why water is a liquid at room temperature?
Hydrogen bonding is the intermolecular force responsible for water being a liquid at room temperature. The hydrogen bonds between water molecules are relatively strong, allowing them to remain in a liquid state rather than vaporizing at room temperature.

Polar covalent molecules are more likely to exist as liquids than gases. Explain this in terms of intermolecular forces?
Polar covalent molecules have dipole-dipole interactions, which are stronger than the London dispersion forces in nonpolar molecules. This results in a higher boiling point, making them more likely to exist as liquids rather than gases at room temperature.
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.
Use kinetic theory to explain boiling?
Boiling occurs when the kinetic energy of the liquid overcomes the intermolecular forces holding the liquid together, resulting in the molecules escaping as vapor. As the liquid is heated, the molecules gain kinetic energy, increasing their movement until they have enough energy to break free from the liquid's surface and escape into the gas phase.
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.
