It is commonly used as a polar solvent and in making other chemicals. For the calculation, assume that at normal filling conditions, the densities of engine coolant and water are 1.11 g/mL and 0.998 g/mL respectively. that means the first employee worked 33 hours at $10.50 per hour, the second worked 40 hours at$18 an hour, and so on. When this polar molecule comes near the non-polar molecule, the electron cloud of the non-polar molecule is distorted in such a way that it also develops partial charges. Intramolecular forces are those within the molecule that keep the molecule together, for example, the bonds between the atoms. P= 1 x 10^5 (triple point) Water molecules participate in multiple hydrogen-bonding interactions with nearby water molecules. Metals tend to make the metallic bond with each other.

Proteins also acquire structural features needed for their functions mainly through hydrogen bonding. Molecular It also has the Hydrogen atoms bonded to an Oxygen atom. Intermolecular forces hold various molecules together, while intramolecular forces hold together atoms in a molecule. b. London forces are negligible in comparison to hydrogen bonding. This allows both strands to function as a template for replication. For example, liquid water forms on the outside of a cold glass as the water vapor in the air is cooled by the cold glass, as seen in Figure 10.3. Intramolecular forces are the chemical bonds holding the atoms together in the molecules.
