Answer:
The given metal is beryllium.
Explanation:
Given data:
Mass of metal = 74 g
Volume of metal = 40 cm³
Which metal is this = ?
Solution:
First of all we will calculate the density.
it is mass divided by volume.
d = m/v
d = 74 g/40 cm³
d = 1.85 g/cm³
In literature it is given that the density of beryllium is 1.85 g/cm³. Thus given metal is beryllium.
<span>All crystalline solids contain vacancies. In fact, vacancies is one of the properties of a crystalline solids, for their presences is what creates their random (entropic) design. Furthermore, it is near impossible to create any solid matter that does not contain vacancies/defects. Vacancies can be created by the absence of an atom during matter creation; thermal vibrations can create such a defect as well.</span>
Answer: The layers are ordered by density, with the least dense layer on top, and the densest layer on the bottom.

Plato
Answer:
The isopropanol evaporated while the water did not because the molecules don't stick together as strongly as the molecules in the water do. The water would need more energy transferred in, in order to evaporate.
