What will be an ideal response? Question 2 A coal-fired plant generates 600 MW of electric power. The plant uses 4.8 106 kg of coal each day. The heat of combustion of coal is 3.3 107 J/kg. The steam that drives the turbines is at a temperature of 300C, and the exhaust water is at 37C. (a) What is the overall efficiency of the plant for generating electric power? (b) What is the Carnot efficiency? Question 3 How many moles are there in 2.0 kg of copper? (The atomic weight of copper is 63.5 and its specific gravity is 8.9.) What will be an ideal response? Question 4 Consider a light bulb, in empty space, radiating 200. watts with its filament heated to 2800.C. Assuming it is a good approximation to a black body. (a) What is the area of the filament? (b) If placed in an oven, with walls at 800.C, what is its net power radiated now? Title: What is the ratio of the speed of sound in air at 0C to the speed at 100 C? What will be an ideal ...
