How is turbocharging in a car engine maximized

What property of the exhaust gas is being used to turn the turbine that runs the compressor Explain. 

If more power is to be gained from this design, what must also accompany the extra supply of oxygen to the combustion chamber  

What property does the compressor alter so that more air can be injected into the combustion chamber Explain. 

Why does the air in the compressor get hot, and why does cooling help to improve the power of the engine  

A gas sample at 40.0°C occupies a volume of 2.32 L. If the temperature Is raised to 75.0°C, what will the volume be, assuming the pressure remains constant
