Why the coefficient of volume expansion of the water different with coefficient of volume expansion of the ethanol?
Since there is extensive hydrogen bonding in case of water (two -OH per molecule) unlike ethanol (which has one -OH per molecule) so the intermolecular force difference is there between water and ethanol. Thus the coefficient of volumetric expansion will also be different, 'coz intermolecular force is a direct variable effecting this coefficient......
What is the dominant intermolecular force in HF?
Hydrogen bonding
Why does heat cause expansion?
becuase of the increase in movement of molecules
What are some ways expansion and contraction could cause safety hazards?
If memory serves me, expansion and contraction can cause stress cracks in many materials, due to breakdown of molecules in the material.
How does gravity affect hydrogen?
Gravity affects hydrogen the same way it does any other element. Hydrogen is lighter than air (nitrogen and oxygen) and therefor is buoyant in air, meaning it floats. No more differently than a piece of wood floats on water. There is no force counteracting gravity's force on the hydrogen, except that nitrogen and oxygen are pulled down to earth displacing the hydrogen. when the hydrogen reaches the outer layer of the atmosphere it will be held there by gravity until some other force (solar wind maybe) strips it away from the earth.
The mysterious force that may be causing the expansion of the universe to accelerate is called?
The current state of affairs with regard to the expansion of the universe point to dark energy as the cause of the expansion of the universe. It is not a force though.
Which inter molecular force would cause the highest melting point?
Hydrogen bonding, which is the strongest of the intermolecular forces.
What was the driving force of the expansion in the American South?
The expansion of cotton plantation.

What expansion was caused by the Industrial Revolution?
the westward expansion was the cause to the industrial revolution.
What force of attraction gives rise to the -helix?
hydrogen bonding
Is a hydrogen a very strong dipole-dipole force?
The hydrogen bond is not strong.
What pushes things apart?
The electromagnetic force can push things apart. This force exists between charged particles and can cause similar charges to repel each other. Additionally, the force of gravity can also push things apart on a cosmological scale due to the expansion of the universe.
Why expansion of water is more than expansion of solids?
The inter atomic force is comparatively less in case of liquid
Is a hydrogen bond a weak molecular interaction?
No, hydrogen bonding is a strong intermolecular force.
Which force help water molecules stick together?
hydrogen bonds
