Answer:
No, because it is an intensive quantity.
Explanation:
According to IUPAC, an intensive quantity is one whose magnitude is independent of the size of the system/sample, on the other hand an extensive quantity is one whose magnitude is additive for subsystems.
Exemples of intensive quantities: temperature, density, concentration.
Exemples of extensive quantities: mass, volume, energy.
The correct label for a solution is; a homogeneous mixture. Option A is correct.
A solution is a type of homogeneous mixture. A homogeneous mixture is one in which the components are uniformly distributed and evenly mixed at a molecular or atomic level. In other words, all parts of the mixture are the same throughout, and there are no visible boundaries or distinct phases between the different components.
In a solution, one or more substances, called solutes, are dissolved in a solvent. The solute(s) become uniformly dispersed at the molecular or atomic level within the solvent, creating a single phase with consistent properties. This even distribution is achieved through the interactions between the solute particles and the solvent particles.
Examples of solutions include;
Saltwater: Sodium chloride (salt) is dissolved in water (solvent) to create a homogeneous solution.
Sugar water: Sucrose (sugar) is dissolved in water to form a homogeneous mixture.
Solutions are essential in various applications, such as in chemistry, biology, medicine, and everyday life. They are commonly encountered and used for various purposes, including in cooking, pharmaceuticals, cleaning agents, and many industrial processes.
Hence, A. is the correct option.

Answer:
Sea floor spreading
Explanation:
In case of a divergent plate motion, two plates move away from another. Due to this motion, there occurs separation of the seafloor, resulting in the addition of new materials to the crust along the mid oceanic ridge. This mid oceanic ridge marks the boundary of separation of the oceanic plates. It often generates deep focus earthquakes and forms volcanoes or chains of volcanic arcs.
Thus, the separation of the two plates under water causes seafloor spreading, and the magma fills the space along the mid oceanic ridge.
Answer:
A kind of nuclear reaction where two light nuclei come in contact with each other to produce a solitary heavier nucleus is known as nuclear fusion. The outcomes of this reaction are usually the unstable compound nuclei, which further gets dissociated into steadier daughter components.
In this reaction, the fusion leads to the discharge of energy as the mass of the novel nucleus is less in comparison to the total of the original masses. There are various kinds of fusion reactions known as deuterium-deuterium reactions, proton-proton chains, and deuterium-tritium reactions.
