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.
HF > HCl > HBr > HI HF is the strongest because F is the most electronegative. by utilising sharing electrons, the atoms that make up the water molecule become charged. there is an charm between the hydrogen atoms of one molecule to the oxygen atom of different molecules that makes water molecules style of sticky without actual forming a bond.
