This certain type of rock is constructive, not only from the fact that it was made up from earthly habits. But also it breaks down very easily, which can help the environment. Therefore a sedimentary rock is constructive.
The term amphoteric describes a substance that can act as both an acid and a base.
The answer to this question will be c
The correct answer is: [C]:
___________________________________________________________
"<span>pressure and the number of gas molecules are directly related."
___________________________________________________________
<u>Note</u>: The conclusion was: "</span> as the pressure in a system increases, the number of gas molecules increases" — over the course of many trials.
This means that the "pressure" and the "number of gas molecules" are directly related.
Furthermore, this conclusion is consistent with the "ideal gas law" equation:
" PV = nRT " ;
____________________________________________________________
in which:
"P = Pressure" ;
"n = number of gas molecules" ;
___________________________________________________________
All other factors held equal, when "n" (the "number of gas molecules")
increases in value (on the "right-hand side" of the equation), the value for "P" (the "pressure" — on the "left-hand side" of the equation), increases.
