Here are the options to the question:
A) The kinetic energy of gas particles will increase.
B) The kinetic energy of gas particles will decrease.
C) The kinetic energy of gas particles will remain unchanged.
D) The gas particles will have no kinetic energy.
<span>E) The kinetic energy of gas particles will be transferred to the container.
</span>
The best answer is:
E. The kinetic energy of gas particles will be transferred to the container

In the question, the number of atoms per unit cell is required for:
A) Polonium (Po)
In polonium, the structure is simple cubic, meaning there are 8 corner atoms, which add up to one atom per unit cell.
B) Manganese (Mn)
The structure of the Mn can be considered to be a body centered cubic (BCC) and the number of atoms for this is 8 corner atoms and 1 central atoms, making a total of 2 atoms per unit cell.
C) Silver (Ag)
Silver has a face centered cubic (FCC) unit cell structure, where there are 8 corner atoms and 6 atoms on the faces, so there are a total of 4 atoms per unit cell.
Explanation:
It is known that entropy is the measure of degree of randomness present in a substance due to the movement of its molecules.
More randomly the atoms are moving from one place to another more will be the entropy of system.
In order to calculate the entropy, we divide the amount of heat transferred by the temperature at which heat transfer occurs.
As the given temperature is 296.95 K and heat of vaporization is 24.8 kJ/mol. Therefore, calculate the molar entropy of vaporization as follows.
Molar entropy of vaporization =
= 0.08351 kJ/mol K
Thus, we can conclude that molar entropy of vaporization of is 0.08351 kJ/mol K.
