Answer:
The characteristic of water that makes this liquid stick to the side of a test tube is called capillarity (Claim).
Explanation:
Water (H₂O) is a polar molecule with the ability to generate van der Waals forces, which is explained by the 4 hydrogen bonds it forms to bind to other substances. The consequence of the forces of the molecular bonds are four properties of H₂O, including surface tension, cohesion, adhesion and capillarity.
- <u>Claim</u>: The characteristic of water that makes this liquid stick to the side of a test tube is called capillarity.
- <u>Evidence</u>: Cohesion and adhesion of water are properties that come from the forces of the molecular bonds of water, and whose effect is the ability of water to wet surfaces and adhere to a tube that contains it, the latter due to capillarity. Capillarity also allows water to rise through the roots and stems of plants, through their thin vascular ducts.
- <u>Reasoning</u>: <u>cohesion</u> in water depends on the force of attraction between H₂O molecules, <u>adhesion</u> is the capacity of H₂O molecules to join other different molecules and —together with <u>surface tension</u>— make H₂O molecules close to the walls of a glass tube adhere to it, which represents capillarity.
The effect of capillarity is more evident when the test tube is of a smaller diameter, although capillarity and adhesion to its walls always exist, and to a greater degree than any other substance.
because the total time for restoration is lengthy, peat can be considered a fossil fuel. The correct option is B.
<h3>What exactly are fossil fuels?</h3>
Fossil fuels are fuels derived from the remains of dead plants and animals that decomposed over time under intense heat and pressure.
Because their replenishment time is longer than a human lifetime, fossil fuels are non-renewable energy sources.
Some examples of fossil fuels are petroleum, coal, etc.
The missing options of the question are:
- peat is a fossil fuel because rewetting it takes only 3-5 years.
- peat is a fossil fuel because the total time for restoration is lengthy.
- peat is not a fossil fuel because it has biologic origins, making it a biofuel.
- peat is not a fossil fuel because humans can promote the replenishment of peat.
The restoration process of peat takes a long time of more than 100 years. As a result, because the total time for restoration is lengthy, peat can be considered a fossil fuel.
Thus, the correct option is B.

The more energy needed, the higher the melting point or boiling point . As metals are giant lattice structures, the number of electrostatic forces to be broken is extremely large, and so metals have high melting and boiling points.
