This is because their tails are hydrophobic and their heads are hydrophilic. Hydrophobic meaning dislikes being near water and hydrophilic meaning likes to be near water. Therefore, they will orientate themselves in such a manner that the heads are facing externally and all the tails are facing together protected by the hydrophilic heads. google a photo of lipid chains in water if you are still confused. I'm not sure if that is what you are asking, but I hope it helps.
Answer:
Intermolecular forces (IMF) (or secondary forces) are the forces which mediate interaction between atoms, including forces of attraction or repulsion which act between atoms and other types of neighboring particles, e.g. atoms or ions. Intermolecular forces are weak relative to intramolecular forces – the forces which hold a molecule together. For example, the covalent bond, involving sharing electron pairs between atoms, is much stronger than the forces present between neighboring molecules. Both sets of forces are essential parts of force fields frequently used in molecular mechanics.

The amount of water evaporating from the ocean is significantly larger than the amount of precipitation falling into the ocean. On a global scale, the ocean loses about 577,000 cubic kilometers of water through evaporation each year, whereas it gains just 505,000 cubic kilometers of water from precipitation.
<h3>The Hydrologic Cycle and its Impact on the Ocean</h3>
Is a natural process involving evaporation, precipitation, transport, and recirculation of water through the land and ocean. The key elements in the hydrologic cycle are water and heat.
The hydrological cycle is important for life on Earth, as it regulates air moisture levels and contributes to:
- Food production
- Energy production
- Aquifer recharge
- Flood mitigation
The hydrological cycle also has a significant impact on the ocean, regulating:
- Salinity levels
- Temperature
- Seawater circulation

The formula is m = D x V
D = <span>13.69 g/cm^3.
</span>V = <span>15.0 cm^3
the mass of the liquid mercury is m= </span>13.69 g/cm^3 x 15.0 cm^3 = 195g
the molar mass of Hg is 200,
1 mole of Hg = 200g Hg, so #mole of Hg= 195 / 200 = 0.97 mol
but we know that
1 mole = 6.022 E23 atoms
0.97 mole=?
6.022 E23 atoms x 0.97 / 1 mole = 5.84 E23 atoms
