The air-fuel mixture enters an automobile engine cylinder at 120°C and 100 kPa. The engine has a compression ratio of 8, which means the air-fuel mixture is compressed to one-eighth the original volume. This process is a polytropic process that follows the equation Pvn = const. Calculate the specific work and the specific heat transfer for this process if
a) n = 1.3,
b) n = 1.4,
c) n = 1.5. Assume constant specific heats.
