As a system increases in volume, it absorbs 52.5 J of energy in the form of heat from the surroundings. The piston is working against a pressure of 0.500 atm. The final volume of the system is 58.0 L. What was the initial vol-ume of the system if the internal energy of the system Decreased by 102.5 J?
Answer to relevant QuestionsWhat is the difference between ΔH and ΔE at constant P? For the following reactions at constant pressure, predict if ΔH . ΔE, ΔH , ΔE, or ΔH = ΔE. a. 2HF(g) → H2(g) + F2(g) b. N2(g) + 3H2(g) → 2NH3(g) c. 4NH3(g) + 5O2(g) → 4NO(g) + 6H2O(g) The specific heat capacity of silver is 0.24 JoC-1g-1. a. Calculate the energy required to raise the temperature of 150.0 g Ag from 273 K to 298 K. b. Calculate the energy required to raise the temperature of 1.0 mole of Ag ...Consider an airplane trip from Chicago, Illinois, to denver, Colorado. List some path-Dependent functions and some state functions for the plane trip. Given the following data: C2H2(g) + 5/2 O2(g) → 2CO2(g) + H2O(l) ΔH = –1300. kJ C(s) + O2(g) → CO2(g) ΔH = –394 kJ H2(g) + ½ O2(g) → H2O(l) ΔH = -286 kJ calculate ΔH for the reaction 2C(s) + H2(g) → C2H2(g)
