Trees use narrow tubes to transport water upward. Which property of water allows the water to rise in these narrow tubes?
A. cohesion of molecules
B. high vapor pressure
C. high boiling point
D. net charge of molecules
Answers
Answer:
high vapour pressure
Explanation:
Answer:
The cohesion of molecules causes the water to transport upward from narrow tubes.
Option (A).
Explanation:
The "force of attraction among molecules of the same substance" known as a "cohesive force". In the case of water, each molecule produce four hydrogen bonds with other water molecules in a tetrahedral configuration.
The hydrogen atoms have "positive charges" while the oxygen atom has a negative charge. Oxygen is more electronegative as compared to hydrogen. Therefore, the electrons they share are closer to oxygen as compare to hydrogen. These are known as polar covalent bonds. The "polarization" inside the molecule enable it to join with adjacent molecules through strong intermolecular hydrogen bonding which happens in the cohesion of liquid.
