Answer:
The change in entropy of gas is
Explanation:
n= Number of moles of gas
Change in entropy of gas =
From the given,
Let "T" be the initial temperature.
Therefore, The change in entropy of gas is
Answer:
Approximately .
Explanation:
If the concentration of ions in a solution is , the of that solution would be .
Note that the base of the logarithm in this calculation should . One way to be sure is to state the base explicitly. Using the change of base rule of logarithms:
.
In this question, it is implied that the concentration of in the given solution is , such that . Using the equations above:
.
Answer:
Well they help us understand the properties of matter of course!
