Consider a well-insulated horizontal rigid cylinder that is divided into two compartments by a piston that is free to. move but does not allow either gas to leak into the other side. Initially, one side of the piston contains 1 m3 of N2 gas at 500 kPa and 80°C while the other side contains 1 m3 of He gas B at 500 kPa and 25°C. Now thermal equilibrium is established H in the cylinder as a result of heat transfer through the piston. Using constant'specific heats at room temperature, determine (a) the final quihbrium temperature in the cylinder and (b) the ' Blasted work potential during this process. What would your answer be if the piston were not free to move? Take T0 = 25°C.
Week 3 Notes Tuesday, September 6, 201611:06 AM Important Points ○ LimitingReagent:Reactant used up first in the reaction ○ Theoretical Yield: Is the amount of productthat would result if all the limiting reagent reacted MAXIMUMobtainable result ○ Actual Yield is the amount of product actually obtained out of a reaction. • More on Titrations ○ Titrationcan be usedin the analysis of acid-baseand redox reactions • Physical Characteristicsof Gases ○ Gases assumethe volume and shapeof their containers ○ Most compressiblestate of matter ○ Gases will mix evenly and completelywhen confinedto the same container ○ Much lower densitiesthan liquidsand solids • Pressure ○ 1 pascal(Pa) = 1 N/m^2
