Question

1) The nickel alloy materials used in 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). Assuming an ideal Carnot efficiency in both cases, what is the increase of efficiency from no coating to coating? (Assume Ambient Temperature Exhaust gases to be 25 °C or 298 K)

*The image includes a photo depicting various turbine blades, possibly illustrating different stages or types of coatings on the blades.*
