2kg of saturated r-134a vapour at 30 °c is compressed adiabatically in a piston. after compression, the temperature is 80 °c and the pressure is 1600 kpa. (a) (4 marks) how much work, in kj, is done during this process? is it work into, or out of, your system? draw your system and state your assumptions. (b) (2 marks) was the compression reversible?

- both b and d.

-since b and d are the closest coastlines then that makes it the most affected.
