Explanation:
It is known that in a simple cubic unit cell the atoms are only present at the corner of the unit cell. This means that there are in total 8 atoms present in a simple cubic unit cell.
Therefore, in one simple cubic unit cell sharing of one atom is only .
Hence, the total number of atoms in a unit cell will be as follows.
= 1
Thus, we can conclude that there is 1 calcium atom present in each unit cell.
The answer for the following problem is mentioned below.
Explanation:
Given:
Initial pressure of the gas () = 1.8 atm
Final pressure of the gas () = 4 atm
Initial temperature of the gas () = 60°C = 60 + 273 = 333 K
To solve:
Final temperature of the gas ()
We know;
From the ideal gas equation;
we know;
P × V = n × R × T
So;
we can tell from the above equation;
<u> P ∝ T</u>
(i.e.)
<em> </em><em> = constant</em>
=
Where;
= initial pressure of a gas
= final pressure of a gas
= initial temperature of a gas
= final temperature of a gas
=
=
= 740 K
<u><em>Therefore the final temperature of the gas is 740 K</em></u>
