The data listed below are claimed for a power cycle operating between hot and cold reservoirs at 1000 K and 300 K, respectively. For each case, determine whether the cycle operates reversibly, irreversibly, or is impossible.
A certain lightbulb has a tungsten filament with a resistance of 17.7 Ω when at 20.0°C and 135 °C when hot. Assume the resistivity of tungsten varies linearly with temperature even over the large temperature range involved here.
As part of the new Bicycle Corps, a solider is pedaling down the road at 25 km/h, holding a missile launcher on his shoulder. The combined mass of the bicycle and the solider is 8o kg, and the single missile in the launcher has a mass of 0.5 kg.
A reversible power cycle receives enery Qh from a hot reservoir at Th and rejects enerfy Qc by heat transfer to a cold reservoir at Tc. If Th= 1200 K and Tc= 300 K, what is the efficiency of the power cycle?
