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.
Best Answer: Van der Waals forces hold the hydrophobic tails of the phospholipid bilayer together, and then hydrogen bonding keeps the hydrophilic heads (opposite the tails) together as well as interact with water surrounding the bilayer, which helps stabilize the lipid bilayer structure.
