Chemistry
(on a 1/2 crosswise) Answer 5.18, 5.19, 5.20 page 189 in Brown, Le May, et al.
5.18 (a) Write an equation that expresses the first law of thermodynamics. (b) In applying the first law, do we need to measure the internal energy of a system? Explain. © Under what conditions will the quantities q and w be negative numbers?
5.19
Calculate delta E, and determine whether the process is endothermic or exothermic for the following cases: (a) A system releases 113 kJ of heart to the surroundings and does 39 kJ of work on the surroundings; (b) q = 1.62 kJ and w = -874 J. © the system absorbs 77.5 kJ of heat while doing 63.5 kJ of work on the surroundings
5.20
For the following processes, calculate the change in internal energy of the system, and determine whether the process is endothermic or exothermic: (a) A balloon is heated by adding 900 J of heat. It expands, doing 422 J of work on the atmosphere. (b) A 50-g sample of water is cooled from 30ºC to 15ºC, thereby losing approcimately 3140 J of heat. (c) a chemical reaction releases 8.65 kJ of heat and does no work on the surroundings
