Configurational Entropy
A system consists of coins. Each coin has a 50-50 probability to show heads or tails. Find the entropy of the case where all coins show heads.
The Boltzmann constant is
We isothermally compress mole of from to How much does the entropy of the gas change?
Assumptions and Details
- is ideal gas
- is Avogadro's number and is the Boltzmann constant.
John set up a password which consists of digits for his new cell phone last night. Upon waking, he finds that he has forgotten his password and only remembers that it was digits long. Find the increase in entropy concerning John's memory of the password.
particles are in a room which is divided into two equal parts. If we consider the macrostate of the even split, what is its entropy?
Assumptions and Details
- The room temperature is
- The Boltzmann constant is
A container is separated by a partition into two equal halves. Each half contains of either or . What is the change in entropy of the total system after the partition is removed?
Assumptions and Details
- , and are ideal gases.
- is Avogadro's number.
