D Question 1 0.5 pts Calculate the rate of heat transfer on a cold day through a rectangular window that is 1.3 m wide and 1.5 m high, has a thickness of 6.6 mm, a thermal conductivity value of 0.27 W/m/C. The temperature inside the home is 21 C and the temperature outside the home is -5C. 2075 W O 207 W O 2400 W 1276 W O 21 W D Question 2 0.5 pts Calculate the cold reservoir temperature of a steam engine that uses hot steam at 450 C and has a Carnot efficiency of 0.700. 563 C O -563 C 0 56.3 C O -56.3 CQuestion 3 0.5 pts What is unreasonable about the temperature calculated in Q2? 0 The temperature is too cold for the output of a steam engine (the local environment). It is below the freezing point of water. 0 The temperature is too hot for the output of a steam engine (the local environment). 0 The answer is reasonable. 0 Question 4 0.5 pts It is unlikely that a process can be isothermal unless it is a very slow process. Is the same true for isobaric and isochoric processes? 0 No, isobaric and isochoric processes can happen at any rate. 0 Yes, isobaric and isochoric processes need to carried out very slow so that the system remains in internal equilibrium always. 0 Only true for isobaric. 0 Only true for isochoric
