Introduction to Water quiz Flashcards

Cohesion and adhesion, low density in solid form, high specific heat and heat of vaporization, and being a universal solvent.

Cohesion is the ability of water molecules to stick to each other due to hydrogen bonding.

Adhesion is the ability of water molecules to stick to other substances that are not water, such as glass.

Surface tension is created by the cohesion and adhesion of water molecules, making it difficult to break the surface of the liquid.

The paperclip can float because it does not break the surface tension created by the cohesion and adhesion of water molecules.

Water adheres to polar and charged molecules.

Hydrogen bonds are responsible for water's cohesion, adhesion, high specific heat, and its ability to act as a universal solvent.

Water's high specific heat helps regulate temperature in the environment, making it stable for life.

Water is considered a universal solvent because it can dissolve a wide variety of substances due to its polarity.

Cohesion refers to water molecules sticking to each other, while adhesion refers to water molecules sticking to other substances.

Water's low density in solid form allows ice to float, providing insulation and a habitat for aquatic life in cold environments.

This measure is called surface tension.

Adhesion allows water to stick to glass.

The root 'co' means together.

This property is known as cohesion.

The majority of the negative charge on a water molecule is located on the oxygen atom, which has a partial negative charge.

Water is a polar molecule because it has polar covalent bonds, where the oxygen atom has a partial negative charge and the hydrogen atoms have partial positive charges, leading to an uneven distribution of charge.

Water is considered a polar molecule due to the difference in electronegativity between oxygen and hydrogen, resulting in partial charges and an uneven distribution of electrons.

Water is a polar molecule because the oxygen atom is more electronegative than the hydrogen atoms, creating partial negative and positive charges and an asymmetrical shape.

In a water molecule, the oxygen atom is labeled with a partial negative charge, each hydrogen atom with a partial positive charge, and the bonds between them are polar covalent bonds. Hydrogen bonds form between different water molecules.

Water is a polar molecule.

In a water molecule, the oxygen atom has a partial negative charge, while the hydrogen atoms have partial positive charges, leading to an uneven distribution of charge.
