0.4kg of gas is compressed adiabatlcaily in a closed system from 20 and 1 bar to afinal pressure of 6bar. Derive from the first principles the relation you may use and determine
i. the ratio of the specific heats y
ii, the gas constant R
iii, the final temperature
iv. the initial volume
v, the final volume
vi. the work done
vii. the heat transfer
viii. the change in internal energy
take cp= 1.008 kJ/kgK and cv = 0.72 kJ/kgK​
