This image shows an overhead view of Atlanta’s buildings, structures, and surrounding areas and a heat map of the area. What is the most likely reason for the high temperature in the regions indicated in dark red? two maps of Atlanta, one showing an overhead view of Atlanta's buildings and structures and other showing the heat levels in the area Atlanta’s roads and buildings absorb more of the Sun’s radiation, causing higher temperatures than in surrounding regions. Atlanta’s trees and forests absorb more of the Sun’s radiation, causing higher temperatures than in surrounding regions. The rural areas around Atlanta absorb more heat than the urban areas, causing an overall increase in the city’s temperatures.

As part of an industrial process, air as an ideal gas at 10 bar, 400k expands at steady state through a valve to a pressure of 4 bar. the mass flow rate of air is 0.5 kg/s. the air then passes through a heat exchanger where it is cooled to a temperature of 295k with negligible change in pressure. the valve can be modeled as a throttling process, and kinetic and potential energy effects can be neglected. (a) for a control volume enclosing the valve and heat exchanger and enough of the local surroundings that the heat transfer occurs at the ambient temperature of 295 k, determine the rate of entropy production, in kw/k. (b) if the expansion valve were replaced by an adiabatic turbine operating isentropically, what would be the entropy production? compare the results of parts (a) and (b) and discuss.

Calculate the mass of an object that has a momentum of 100kg x m/sec and velocity of 4 m/sec

A0.750 kg aluminum pan is removed from the stove and plunged into a sink filled with 10.0 kg of water at 293 k. the water temperature quickly rises to 297 k. what was the initial temperature of the aluminum pan? the specific heat of aluminum is ca = 900 j/(kgk) and water is cw = 4190 j/(kgk)
