Unformatted text preview: Department of Chemical Engineering ChE 110A University of California, Santa Barbara Winter 2011 Problem Set No. 2 Due: Wednesday, January 12, 2011 Objective : To understand and perform calculations using fundamental mechanical relations in thermodynamics. Note: Numerical values for some problems have been changed from those in the book. Problem 1 (thought problem) Consider two ways in which you might add energy to a gas inside a piston: (1) compressing the gas to a smaller volume, and (2) heating the gas by raising the temperature of the piston. If you were able to zoom in and watch these two process at the molecular level, both would involve the transfer of kinetic energy due to collisions between moving and vibrating atoms in the piston with atoms in the gas (similar to billiard balls). What, therefore, is the difference between compression and heating at the molecular level? Problem 2 ( Smith, van Ness, Abbott, 1.8, page 16) The reading on a mercury manometer at 70 F (open to the atmosphere at one end) is 23.1 The reading on a mercury manometer at 70 F (open to the atmosphere at one end) is 23....
