Examples of intensive properties include:
- Boiling point
- Density
- State of matter
- Color
- Melting point
- Odor
- Luster
- Hardness
- Ductility
- Malleability
Intensive properties can be used to help identify a sample because these characteristics do not depend on the amount of sample, nor do they change according to conditions.
Extensive Properties
Extensive properties do depend on the amount of matter that is present. Examples of extensive properties include:
- Volume
- Mass
- Size
- Weight
- Length
While extensive properties are great for describing a sample, they aren't very helpful identifying it because they can change according to sample size or conditions.
Way To Tell Intensive and Extensive Properties Apart?
One easy way to tell whether a physical property is intensive or extensive is to take two identical samples of a substance and put them together.
Explanation and Examples of Physical Properties
If this doubles the property (e.g., twice the mass, twice as long), it's an extensive property. If the property is unchanged by altering the sample size, it's an intensive property.
Answer:
Learning involves of knowledge acquisition through study, being taught, or experience. On the other hand, cognition is the process of knowledge acquisition and understanding through our senses, experiences, and thoughts. Cognition involves learning. Learning on the other hand requires cognition. For example, when you hear a new information, your brain goes through a series of cognitive processes. It is this processes that makes you decipher or understand the new information and that results in learning.

Friction and Tectonic Forces
Some of the first forces that may begin the process of breaking down rock are underground tectonic forces. As the plates of the Earth's crust move against one another, they create friction and pressure, and rocks caught between these plates may fracture and grind themselves into smaller fragments. If any of the broken pieces make their way to the surface, they may experience weathering, the next step in the process of breaking down.
Chemical Weathering
Chemical weathering occurs when a rock encounters a liquid or gas that damages it. For instance, any rock exposed to air undergoes oxidation, in which the oxygen in the air reacts with metallic elements to cause rust. This process gives soil that is rich in iron oxides a reddish color. Similarly, exposure to water can alter certain types of minerals, as with hydrolysis that changes feldspar into clay. Feldspar is the most common mineral found in rock. Dissolved carbon dioxide in rainwater can form carbonic acid, which will break down minerals like calcite -- a calcium-containing mineral found in limestone. These chemical processes can further weaken rocks, making them more susceptible to other forces.
Physical Weathering
Physical forces can also weather rocks. Water that freezes inside the cracks of rock expands, pushing apart the mineral deposits and causing it to fracture. Similarly, the roots of plants can work their way into rocks as they grow, and the pressure caused by their expansion can break apart the rock into smaller pieces. Temperature extremes can cause rocks to expand and contract, increasing the stress on fracture lines and causing them to break apart.
Wind and Water Erosion
Once weathering has damaged rocks and broken them down, the forces of erosion can take over to redistribute the material. Wind and water passing over rocks can pick up small particles, carrying them downstream away from the original deposit. Over time, erosion can turn mountains into hills, carry topsoil into the oceans, and carve channels into solid stone. For instance, scientists believe that one of the primary forces that shaped the Grand Canyon was erosion -- due to the waters of the Colorado River carrying away lightweight soil and limestone from the surface, and the winds blowing dust and smaller particles through the resulting channels.
