Question

vocabulary: define the following terms in your own words. 1. capillary action answer 2. polar molecule answer 3. ionic bond answer 4. covalent bond answer 5. hydrogen bond answer 6. adhesion answer 7. cohesion answer

Explanation:

1. Capillary Action: The ability of a liquid to flow in narrow spaces without the assistance of, or even in opposition to, external forces like gravity. It occurs due to the combination of adhesive forces (attraction between liquid and solid surfaces) and cohesive forces (attraction between liquid molecules).
2. Polar Molecule: A molecule in which the distribution of electrons is not even, resulting in a positive end and a negative end. This is due to differences in electronegativity between the atoms in the molecule.
3. Ionic Bond: A chemical bond formed by the complete transfer of one or more electrons from one atom to another, creating positively - charged cations and negatively - charged anions that are held together by electrostatic forces.
4. Covalent Bond: A chemical bond where atoms share one or more pairs of electrons to achieve a stable electron configuration.
5. Hydrogen Bond: A weak electrostatic attraction between a hydrogen atom covalently bonded to a highly electronegative atom (such as nitrogen, oxygen, or fluorine) and another electronegative atom.
6. Adhesion: The attraction between different substances, such as a liquid and a solid surface.
7. Cohesion: The attraction between molecules of the same substance.

Answer:

1. Capillary Action: The movement of liquid in narrow spaces due to adhesive and cohesive forces.
2. Polar Molecule: Molecule with uneven electron - distribution and distinct positive and negative ends.
3. Ionic Bond: Bond formed by electron transfer creating ions held by electrostatic forces.
4. Covalent Bond: Bond where atoms share electron pairs.
5. Hydrogen Bond: Weak attraction between hydrogen and another electronegative atom.
6. Adhesion: Attraction between different substances.
7. Cohesion: Attraction between like - substance molecules.
