Using the Energy Balance with the Ideal Gas Model 3.81 Ammonia is contained in a rigid, well-insulated container. The initial pressure is 138 kPa, the mass is 0.05 kg, and the volume is 0.054 m. The gas is stirred by a paddle wheel, resulting in an energy transfer to the ammonia of magnitude 21 kJ. Assuming the ideal gas model, determine the final ting temperature of the ammonia, in K. Neglect kinetic and Thun potential energy effects. behavior
