1.	In apetrolengine(internal combustionengine )air atatmosphericpressureandtemperatureof 20^(@)Cis compressedin thecylinder by thepistonto 1//8 of itsoriginalvolume. Calculatethetermperature of thecompressedair .
Answer» Solution :`T_(1)=20^(@)C=20+273K, V_(1)=1m^(3), V_(2)=(1)/(8)V_(1)m^(3), gamma=1.4` FORM equation of adiabatic process `TV^(gamma-1)="constant"` `T_(1)V_(1)^(gamma-1)=T_(2)V_(2)^(gamma-1)` `T_(2)=((V_(1))/(V_(2)))^(gamma-1)T_(1)` `T_(2)=((1)/(((1)/(8))))^(1.4-1)xx298=(8)^(0.4)xx293` `=673.1K=673.1-273,T_(2)=400^(@)C`
