σ= 5.67051×10 -8 W/m2 K4 . R = 8.31 J/mol.K
1) An insulated chamber is divided into equal volumes. The left volume contains an ideal gas at temperature T₀. And the right volume is evacuated.
A small hole is opened between the two volumes allowing the gas to flow and the system comes to equilibrium. No exchanged with the walls. Find the final temperature of the system?


2) When an electric current is maintained in an electrolytic cell of slightly acidic water and 1 mol of water is electrolyzed into hydrogen and oxygen , 2F (faradays) of charge are transferred through a source of emf E
(If 96,500 C/mol). The energy change of the system is +286,500 J , and 50,000 J , of heat is absorbed what is E?
