Unformatted text preview: 1 Name ______________________________ _ 09106 Spring 2011 Recitation ( CIRCLE ONE TA and ONE TIME ): Christian Steve Brendan 6:30 7:30 Problem Set 1 DUE Fri. 1/21 (20 points) PART I 1. 10.0 mol of H 2 gas (as always, considered ideal) is initially contained in a 50.0 L vessel at a pressure of 3.00 atm. The average molar heat capacity of H 2 at constant pressure is 29.3 J K1 mol1 in the temperature range involved. The gas is cooled reversibly at constant pressure from its initial state to a volume of 30.0 L. Calculate the following for this process: (a) The final temperature. (b) The work done. (c) E for the gas (d) q for the gas. (e) H for the gas. 2 2. A 505 g piece of copper tubing is heated to 99.9C and placed in an insulated vessel contain ing 59.8 g of water at 24.8C. Assuming no loss of water and a heat capacity for the vessel of 10.0 J/K, what is the final temperature of the system? [ c of copper = 0.387 J/(gdegree)] 3 3. A 1.50 mol sample of an ideal gas expands reversibly in an insulated vessel to twice its original A 1....
