Molecular polarity has a direct effect on the behavior of molecular compounds. The attractive forces between polar molecules are
_____ than those between nonpolar molecules. It therefore takes _____ energy to separate polar molecules from each other, and a polar compound will have a _____ boiling point than a nonpolar compound of similar size.
Molecules are held together by intermolecular forces. These are forces that act between molecules in a particular state matter. Intermolecular forces depend on the nature of the molecule.
For polar molecules, the intermolecular forces are stronger thus it takes more energy to separate them leading to a higher boiling point of polar molecules irrespective of their molecular mass.
Answer: Solving by the method of exponential growth. bacteria = 2 after one hr = 2² = 4 after 2nd hr = 2³ = 8 after 3rd hr = 2⁴ = 16 after 4th hr = 2⁵ = 32
