Answer:
Explanation:
Solids are divided into two main categories, crystalline solids and amorphous solids, based on how the particles are arranged.
Crystalline solids, or crystals, are regarded as "true solids." Minerals are crystalline solids. Common table salt is one example of this kind of solid. In crystalline solids, the atoms, ions or molecules are arranged in an ordered and symmetrical pattern that is repeated over the entire crystal.
Crystalline solids also exhibit anisotropy. This means that properties such as refractive index (how much light bends when passing through the substance), conductivity (how well it conducts electricity) and tensile strength (the force required to break it apart) will vary depending on the direction from which a force is applied. Crystalline solids also exhibit cleavage; when broken apart, the pieces will have planed surfaces, or straight edges.
There are four types of crystalline solids: ionic solids, molecular solids, network covalent solids and metallic solids.
In amorphous solids (literally "solids without form"), the particles do not have a repeating lattice pattern. They are also called "pseudo solids." Examples of amorphous solids include glass, rubber, gels and most plastics. An amorphous solid does not have a definite melting point; instead, it melts gradually over a range of temperatures, because the bonds do not break all at once. This means an amorphous solid will melt into a soft, malleable state (think candle wax or molten glass) before turning completely into a liquid.
Amorphous solids have no characteristic symmetry, so they do not have regular planes of cleavage when cut; the edges may be curved. They are called isotropic because properties such as refractive index, conductivity and tensile strength are equal regardless of the direction in which a force is applied.
Answer:
it is not right because they aint the same?!!!!?
Answer:
B. to narrate past events
Explanation:
The verb tenses used in the following sentence from the story: "In the past they had sometimes been treated to three-legged creatures from Venus" are used to narrate past events.
This is because, events that have already happened are being narrated.
The correct answer is B. adjective phrase.
While writing my report, I found the information on this website to be very helpful.
In order to find out what kind of phrase 'on this website' is, we have to ask what its function in the sentence is. In this case, it is describing something, saying that it is on this website. Now, we have to determine what it is describing, because adverbs and appositives also describe. In order to find out what it is describing, ask yourself 'What is ____?'.
What is on this website?
Information is on this website.
Therefore, 'on this website' is describing 'information'. Because 'information' is a noun, the phrase 'on this website' must be an adjective phrase, because adjective phrases describe nouns.
An example of an adverb phrase would be:
The dancers moved very gracefully.
The dancers did what very gracefully?
The dancers moved very gracefully.
Therefore, 'very gracefully' is an adverb phrase because 'moved' is a verb. This is also the case when the phrase is describing an adjective or another adverb.
Appositive phrases are difficult because they also describe nouns; however, appositives are separated from the rest of the sentence by a set of commas, and serve to rename the noun they are describing.
Here is an example:
The girl, my cousin, walked over to me.
Who is my cousin?
The girl is my cousin.
Therefore, 'my cousin' is describing 'girl'. Because girl is a noun, it is either an appositive phrase or an adjective phrase. Since 'my cousin' is separated from the rest of the sentence by commas and is renaming the noun, 'girl', it must be an appositive. Therefore, 'my cousin' is an appositive phrase.
Hope this helps!
