Intensive Vs Extensive Properties Quiz

Conductivity refers to the ability of a substance to allow the flow of energy or electricity. It is a measure of how well a material can conduct electrical current. Substances with high conductivity, such as metals, allow electricity to flow easily, while substances with low conductivity, such as rubber or plastic, do not allow electricity to flow easily. Conductivity is an important property in various fields, including electrical engineering, chemistry, and materials science.

Luster refers to the way a substance reflects light. It describes how shiny or dull the surface of a substance appears. The higher the luster, the more reflective and shiny the substance is. Conductivity, hardness, and volume do not directly relate to the shininess of a substance.

Mass is an extensive property because it depends on the amount of matter present in a substance. It is a measure of the total mass of an object or sample, and it increases or decreases proportionally with the quantity of matter. In other words, if you double the amount of a substance, its mass will also double. Extensive properties like mass are additive and can be used to characterize and compare different samples or objects.

Malleability refers to the ability of a substance to be beaten or hammered into thin sheets without breaking or shattering. It is a property that is commonly observed in metals, such as gold and silver, which can be easily shaped into different forms. Malleability is an important characteristic in various industries, including metalworking and jewelry making, as it allows for the creation of intricate designs and shapes.

The mass of a substance divided by its volume equals density. Density is a physical property of a substance that represents the amount of mass per unit volume. It is calculated by dividing the mass of the substance by its volume. Density is commonly used to identify and compare different substances, as substances with different densities will have different weights for the same volume.

Weight is an extensive property because it depends on the quantity of matter present. It increases or decreases with the amount of substance being considered. For example, if we have two objects with the same material, the one with more mass will have a greater weight. In contrast, intensive properties like boiling point and density do not depend on the amount of substance but rather on its nature or composition. Hardness is an intensive property that is measured on the Mohs hardness scale.

Ductility refers to the ability of a substance to be drawn into thin wires without breaking or losing its strength. This property is commonly observed in metals, such as copper and aluminum, which can be easily stretched into long, thin wires. Ductility is an important characteristic in various industries, including electrical wiring and jewelry making.

Extensive properties are those that depend on the amount of matter present. Mass is an extensive property because it increases with the amount of matter. Hardness is an intensive property. For example, a diamond is rated 10 on the Mohs Hardness Scale regardless of its size. Intensive properties, on the other hand, do not depend on the amount of matter present. Therefore, the correct answer is extensive.

Velocity is not an extensive property. Extensive properties are dependent on the amount of substance present, while velocity is a measure of the rate of change of displacement of an object with respect to time. It does not depend on the amount of substance, but rather on the object's motion. Therefore, velocity is not an extensive property.

Concentration is considered an intensive property because it does not depend on the amount or size of the substance being measured. Intensive properties are independent of the quantity of the substance and remain constant regardless of the sample size. In the case of concentration, it refers to the amount of solute present in a given volume of solvent, and this ratio remains the same regardless of the amount of the solution. Therefore, concentration is an example of an intensive property.
