compressing air in a compressor-what is the thermodynamics of it?

[chhitiz]

when we compress air, like, say in a compressor used in i.c. engines, is it an adiabatic process?

If the compressor is well enough insulated or the process happens fast enough to not allow heat transfer between the environment, then yes, it would be an adiabatic compressor.
