1) The nickel alloy materials using on the hot section of a jet engine can withstand temperatures of up to 1100 °C (2012 °F or 1373 K) if you add a ceramic coating that number goes up to 1300 °C (2372 °F or 1573 K).

(a) New-age power plants are often times forced to limit hot reservoir temperatures in steam engines to ~280 deg C due to the lack of sufficient heat-resistant materials. Assuming a reversible Carnot steam engine operating at this temperature uses room temperature (20 deg C) as the cold reservoir temperature, determine the total work produced by the system per complete cycle.

Note that the following relationships are for an ideal gas with an initial state (P1, V1, T₁) and a final state (P2, V2, T2) where W is the work done on the gas, Q is the heat transferred to the gas and AU is the change in internal energy of the gas.
