Answer:
Explanation:
Data:
p₁ = 1 bar; V₁ = 5 L; T₁ = 0 °C
p₂ = 1 bar; V₂ = ?; T₂ = 45 °C
The pressure and the number of moles are constant, so, to calculate the volume, we can use Charles' Law.
Calculations:
(a) Convert temperatures to kelvins
T₁ = (0 + 273.15) K = 273.15 K
T₂ = (45 + 273.15) K = 318.15 K
(b) Calculate the new volume
1.) Gas given off
2.) precipitate formed
3.) large amount of heat given off
4.) Color change
Answer: Heres the answers

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.
