Find amount of heat transfer and identify if it is heat loss
A piston-cylinder device contains air initially at 150kPa, 20oC and 0.5m3. The air is now compressed in a polytropic process to 400kPa and 140oC. Determine the amount of heat transfer and identify if it is the heat loss or gain during this process.
