Finger [1]

Answer:

It will not unless it contains as much energy as the cup of tea. So a tiny spark may be at 1,000 Celsius  but a whole cup of tea at 90 Celsius  will deliver far more heat (energy) to the skin as the spark.

NOT BIOLOGY ITS PHYSICAL SCIENCE how are the allotropes of carbon similar and how are they different?
Rashid [163]

Allotropes of carbon includes substances such as graphite, diamond or buckminsterfullerene.



They’re all similar in the thing that they’re all made out of carbon only.


However, their structure is different, such as graphite has a layer structure, diamond has a tetrahedral structure, and buckminsterfullerene has a spherical structure.  



Since they have different structures, they have different physical properties too. For example, diamond is hard because all the carbon atoms in the structure is held together by strong covalent bonds, while graphite are graphene layers that are held by weak intermolecular forces which makes the layers slide over each other easily thus making graphite soft.

A scientist studying the star Alpha Centauri would probably rely on _____ to gather data. A. the Internet B. encyclopedia articl
jeka57 [31]

D. descriptive investigations

Explanation:

A scientist studying the star Alpha Centauri would probably rely on descriptive investigation to gather data.

In descriptive investigation, experiments cannot be performed since the subjects cannot easily be manipulated or they are far too inaccessible. This form of investigation is based on indirect qualitative investigation of a phenomenon.

  • Alpha Centauri is a distant star several light years away from the vicinity of the scientist.
  • The best way to investigate this distance body is to make inferences from the evidence gathered from observatory stations using telescopes.
  • Astronomers can collect different information and give vivid description of the distant start.
  • It is highly impossible to make comparisons and alter variable in this kind of investigation.
