Some examples of physical properties include things like odors, mass, density, color, conductivity and volume. Physical properties of matter have two main categories: intensive properties and extensive properties.Know More
Intensive properties are ones that do not depend on the amount of the substance. An intensive property is present no matter the amount of that substance that exists. The two most common intensive properties are odor and color. Luster is an intensive property that represents how shiny a substance is. Boiling points, melting points and freezing points are all also examples of intensive physical properties. These are the temperatures a substance needs to reach in order to change its state of matter. Density, malleability, hardness, conductivity and ductility are also examples of intensive properties of matter.
Extensive properties, on the other hand, are ones that rely on the amount of a substance present in order to be measured. Mass, an extensive property, is the measurement, usually in grams, of how much matter is in an object. Similarly, weight is an extensive property and is a measurement of the gravitational force that the earth has on an object. Lastly, volume is the measurement of the amount of space a substance or object takes up.Learn more about Physics
Entropy is seen in situations that involve the dispersal of energy from a concentrated state to a less concentrated one, such as a hot pan cooling down, a tire blowing and releasing its air, the rusting of metal or cream mixing with coffee in a mug. These examples follow the definition of entropy, which is a measure of how energy and matter are dispersed within a system.Full Answer >
A bullet fired from a gun is an example of mechanical kinetic energy, while the gunpowder before firing is an example of chemical potential energy. Kinetic energy is the energy of a particle or wave in motion, while potential energy is the potential of this particle or wave to move.Full Answer >
An example of punctuated equilibrium is human evolution, in which species seem to remain stable for very long spans of time and then abruptly develop into new species, or in the rapid evolution of species isolated on islands. Punctuated equilibrium is a modified version of Darwin's law.Full Answer >
Inelastic collisions are collisions where the kinetic energy is not conserved during the incident, but the total energy and momentum is conserved. For example, when a car collides with an immovable object, it is stopped, and its kinetic energy is lost.Full Answer >
