A Styrofoam cup holding 104 g of hot water at 1.00 x 102°C cools to room temperature, 26.0°C. What is the change in entropy of the room? (Neglect the specific heat of the cup and any change in temperature of the room. The specific heat of water is 4,186 J/(kg . °C).) J/K Need Help? Mead
In one cycle, a heat engine absorbs 520 J from a high-temperature reservoir and expels 310 J to a low-temperature reservoir. If the efficiency of this engine is 59% of the efficiency of a Carnot engine, what is the ratio of the low temperature to the high temperature in the Carnot engine?
In one cycle a heat engine absorbs 530 J from a high-temperature reservoir and expels 320 J to a low-temperature reservoir. If the efficiency of this engine is 58% of the efficiency of a Carnot engine, what is the ratio of the low temperature to the high temperature in the Carnot engine? please show every step, thanks
