The cylinder of a turbocharged diesel engine is filled with air at 30.0 psia and 250°F. When the intake valve closes, cylinder volume is 60.0 in3. The piston moves upward un-til cylinder volume is 4.00 in3, at which time pressure is 1100 psia.
a) What is the mass of air in the cylinder?
b) What is the temperature in the cylinder when the volume reaches 4.00 in3?
