Development of the Modern Freezer. Bacteria are usually the cause of food decay, but they can't grow as well or at all in freezing temperatures, which are at 32 degrees Fahrenheit (0 degrees Celsius) or lower.
HF- polar molecule: dipole-dipole forces. There are also dispersion forces and H bond between HF. BF3- nonpolar: dispersion forces. Ar- Dispersion forces between Ar atoms.
When someone says the intermolecular forces they are talking about how each molecules of any substance (in this case water) interact with each other. Each substance or thing that we see has intermolecular forces. Answer: The intermolecular forces means how strong the bonding is between each individual molecule. This strength of the bonds determines whether a substance is a solid, liquid, or gas at room temperature. Intermolecular forces are the forces of attraction between molecules. They include:- Hydrogen bonding, van der waals forces which includes dipole -dipole interactions, dipole -induced dipole interactions, instantaneous dipole interactions (London dispersion forces) Intermolecular force - or physical force - is the attraction between molecules.
