Yes, Bobby is correct
Explanation:
Anomalously high boiling point of water is as a result of the intermolecular forces between the molecules of water.
The intermolecular forces found in water are the very strong hydrogen bonds. The bulk of the physical properties of matter are due to the intermolecular forces that they possess.
- Hydrogen bonds are stronger than van der waals forces and they are more effective in binding molecules together into larger units.
- Substances whose molecules join via hydrogen bonds have higher boiling points i.e lower volatility than those with van der waals forces.
- Hydrogen bond is actually an electrostatic attraction between hydrogen atom of none molecule and the electronegative atom(O or N or F) of a neighboring molecule.

Answer: -
The next low tide occur at 12 noon, because the coastline will turn 90 degrees from the moon.
Explanation: -
Time taken for the earth to rotate = 24 hours.
Each day there are two high tides and low tides.
Thus the duration between two high tides is 12 hours and between 1 high tide and 1 low tide is 6 hours.
Thus the time of next low tide is 6 am + 6 hours = 12 noon.
Now in 24 hours the coastline turns 360 degrees.
In 6 hours it will travel (360 x 6) / 24 =90 degrees.
Thus the next low tide occur at 12 noon, because the coastline will turn 90 degrees from the moon.
6+2=115 and its good it took test
