Based on the observations from, the substance that water is more attracted to are polar substances.
<h3>
What is the Polarity of water?</h3>
Water is a compound made up of 2 atoms of hydrogen and 1 atom of oxygen.
Water molecule is polar due to the unequal sharing of electrons between the atoms and the unsymmetrical shape of the molecule.
Since water molecules are polar, they are more attracted to molecules that are also polar.
Thus, based on the observations from, the substance that water is more attracted to are polar substances.

Answer:
B. convection because warm air rises and cool air sinks.
Explanation:
The processes that enables birds to fly to higher altitudes without flapping their winds while riding air thermals is called convection.
Convection is one of the forms of heat transfer usually found in gases and liquids.
- In convection density differences due to temperature changes causes the circulation.
- Warm air is less dense and it is hotter.
- It rises up from the surface where it is warmed
- Cold air sinks to replace the warm air. Cold air form when the air loses its energy to the surrounding.
- By virtue of this, birds are able to take advantage of it for their flight.
Answer:
<h3>The answer is 0.23 moles</h3>
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
We have the final answer as
<h3>0.23 moles</h3>
Hope this helps you
