- In a cylindrical container with a base area A, there are Nmonatomic gas particles at temperature T which are ideal. The upperpart of the container is closed with a lid which has a weight M andcan moves upward and downward without friction . There is vacuum onthe lid and the whole system is under gravity.
a) Calculate the balance position of the lid. When performing thiscalculation, you can assume that the cover is quite narrow in thevertical.
- Suppose the system is completely isolated from the outside,doubling the weight of the lid (2M).
b) Determine the new temperature T* of the gas and the newequilibrium position of the lid.
c) Calculate the change in the entropy of the gas.
