Temperature and pressure at the earth's surface are minimal compared to what they are at depth. With sediments, they become converted to rocks or become lithified by burial which subjects them to higher temperature and pressure. If the temperature and pressure become too great, then the sediments will be converted to metamorphic rocks. Basically the rocks or sediments are changing in order to be in equilibrium with the new conditions.
Answer:
<h3>A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance. Physical properties include color, density, hardness, and melting and boiling points. A chemical property describes the ability of a substance to undergo a specific chemical change.</h3>
Explanation:
<h3>Physical properties can be broken down into extensive and intensive properties. Intensive properities can help you identify a substance. ... Other examples of intensive properties include density , solubility, color, luster, freezing point and malleability</h3>
<h3>Luster. ... Luster is how the surface of a mineral reflects light. It is not the same thing as color, so it crucial to distinguish luster from color. For example, a mineral described as “shiny yellow” is being described in terms of luster (“shiny”) and color (“yellow”), which are two different physical properties.</h3>
Answer:
A buffer solution is a mixture of two pair salts to maintain a stable pH.
Explanation:
This mixture is made always with a complementary pair of salts (one acid an another basic).
Example:
Acetic Acid (CH3COOH) and Sodium Acetate (NaH3COO).
So when you add a little bit more acid to this mixture, the basic part of the buffer, in this case the Sodium Acetate, will neutralize it and the pH will remain the same.
On the other hand, if the mixture receives some basic substance, the acid part of the buffer, the acetic acid, will neutralize it, so again the pH will remain the same.
Answer:
Computer hard drives use magnetism to store the data on a rotating disk. More complex applications include: televisions, radios, microwave ovens, telephone systems, and computers. An industrial application of magnetic force is an electromagnetic crane that is used for lifting metal objects.
