## Answers

The approximate final temperatures in Kelvin at the end of the compression and expansion processes are respectively**500 and 900**

**Ideal Brayton cycle**

At the end of compression, temperature.

**Barton Cycle**

The Brayton cycle is a thermodynamic cycle named after George Bailey Brayton that describes the workings of a constant-pressure heat engine. The original Brayton engines used a piston compressor and piston expander, but more modern gas turbine engines and airbreathing jet engines also follow the Brayton cycle. Although the cycle is usually run as an open system (and indeed must be run as such if internal combustion is used), it is conventionally assumed for the purposes of thermodynamic analysis that the exhaust gases are reused in the intake, enabling analysis as a closed system
