The pressure in a constant-volume gas thermometer is 0.700 atm at 100☌ and 0.512 atm at 0☌. the pressure rises until a liquid-gas equilibrium is reached. the pressure rises until it reaches 1 atm 2. When solid CO2 (dry ice) is allowed to come to equilibrium in a closed constant volume container at room temperature (300K), 1. (Remember to includeĬonsider the reaction: SO2 (g) + NO2 (g) => SO3 (g) + NO (g) At T = 1000 K, where the reaction is exothermic with an equilibrium constant K = 9.00 The reaction vessel is charged initially with all four gases, each at a pressure of 0.5 atm. What is w when 3.37 kg of H2O(l), initially at 25.0oC, is converted into water vapour at 111oC against a constant external pressure of 1.00 atm? Assume that the vapour behaves ideally and that the density of liquid water is 1.00 g/mL. (a) at 75☌ and 1 atm: 1 mol H2O(l) or 1 mol H2O(g) (b) at 5☌ and 1 atm: 50.0 g Fe(s) or 0.80 mol Fe(s) (c) 1 mol Br2(l,1 atm, 8☌) or 1 mol Br2(s, 1 atm, -8☌)Īn ideal gas is allowed to expand isothermally from 2.00 L at 5.00 atm in two steps: a) against a constant external pressure of 3.00 atm, followed by b) against a constant external pressure of 2.00 atm.

Calculate the work, w, if the gas expands against a constant external pressure of 1.00 atm to a final volume of 20.0 L. In the process, the volume changes from 1.00Ĭonsider an ideal gas encloesd in a 1.00 L container at an internal pressure of 10.0 atm. One gram of water changes from liquid to solid at a constant pressure of 1.00 atm and a constant temperature of 0�C.
