Explanation:
As a substance melts, and goes from a solid to a liquid state, the kinetic energy of the molecules increases, and the molecules move faster, and they separate further and further away from each other. The intermolecluar forces holding the molecules together become weaker
Answer: The charge on the plates are 88.4 picafarad
Explanation:The equation used in measuring charge in a plate is given as:
C=Q/V =E A/D
Where E= dielectric content
A= Area of plates
d= distance between plates
Using dielectric constant for Air=8.84×10-12F/m
A=100cm2=0.01m2
d=10mm=0.001m
C= 8.84×10-12×0.01/0.001
C= 88.4 picafarad
<span>The slim exit of the
column is first persisted with glass wool or a permeable plate in order to sustain
the column packing element and keep it from getting out of the tube. Then the
adsorbent solid, which is usually a silica, is firmly packed into the glass
tube to make the separating column. The packing of the non-moving phase into
the glass column must be done with precaution to create an even distribution of
material. An even distribution of adsorbent material is very important to lessen
the existence of air bubbles and/or channels inside the column. To finish
preparing the column, the solvent to be used as the mobile phase is delivered
through the dry column. Then the column is said to be "wetted" and
the column must stay wet throughout the entire procedure. Once the column is properly
prepared, the sample to be separated is placed at the top of the wet column.</span>
Answer:
Rock
Explanation:
Rock -
It refers to the naturally occuring mass of mineral , with a uniform chemical composition , is referred to as a rock .
In the crust of the Earth , the composition is by the igneous rocks .
<u>There are three main type of rocks , i.e. , </u>
- sedimentary rocks ,
- metamorphic rocks ,
- igneous rocks .
Hence , from the given information of the question ,
The correct term is rock.
3A (also known as group 13) all the elements have 3 electrons in their outer most shell thats why theyll be divided into the ns2 and the np1
