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.
INTERMOLECULAR FORCES AND BONDING. The forces holding molecules together are generally called intermolecular forces. there are strong bonds such as covalentor ionic bonds and weak bonds such as dipole-dipole interactions the London dispersion force and hydrogen bonding covalent bondã ionic bond ãH bond ãdipole-dipole forces âLondon forces.
