Compressing gas with piston: reasons for temperature increase?

[QUOTE="Anand Sivaram, post: 6540856, member: 586676"] You can compress the gas typically in two processes - adiabatic compression or isothermal compression. Boyle's law speak only about isothermal compression. For Adiabatic process the equation is PV^(gamma) = Constant. For example, you compress air at 1 bar and 300K temperature to a volume of 1/10. If it is isothermal compression you could get a pressure of 10 bar after compression with the same 300K temperature. But, if it is Adiabatic compression using the Adiabatic equation, you would see that the pressure would be rather 25 bars. Now, using the Universal gas law with volume 1/10, pressure 25 bars the new temperature would be around 750K. That is the difference. [/QUOTE]
