Answer:
Electrostatic Van de Waals forces act between molecules to form weak bonds. The types of Van der Waals forces, strongest to weakest, are dipole-dipole forces, dipole-induced dipole forces and the London dispersion forces. The hydrogen bond is based on a type of dipole-dipole force that is especially powerful. These forces help determine the physical characteristics of materials.

Explanation:
Completing the statements:
Water's boiling point would have been close to -70°C. Ice would sink in water. Water would release little heat to warm land during the winter. Ice is less dense than water because of the hydrogen bonding that forms a hexagonal structure in water.
The unique property of water is as a result of its hydrogen bonding. Water is a polar covalent compound. Like most covalent compound, water would have naturally had a very low boiling point.
The intermolecular forces all hydrogen bonding gives water its unique nature.
Hydrogen bond is formed by an attraction between hydrogen one water water molecule and more electronegative atom on another molecule usually oxygen, nitrogen and fluorine.
They form very strong intermolecular interaction responsible for the behavior of water.
The higher specific heat capacity of water is due to this bond. It absorbs a lot of heat and does not release them on time. This causes water release heat during winter.
Water has a hexagonal shape or structure linking each molecules.

Answer:
<h2>4.55 L</h2>
Explanation:
The new volume can be found by using the formula for Boyle's law which is
Since we're finding the new volume
We have
We have the final answer as
<h3>4.55 L</h3>

Answer:
D. 4.75 m/s west
Explanation:
You can immediately get the answer once you know the formula for<em> velocity.</em>
- The formula for velocity is: Velocity (V) =
The distance is 95 meters while the time is 20 seconds. All you have to do is to divide <u>95 meters by 20 seconds</u>.
Let's solve:
- V =
- V =
- V = 4.75 meters per second
Since Brenda is going west with her her skateboard, then you have to add <em>west </em>as her direction.
Brenda's velocity is 4.75 m/s west.
