Air contained in a variable-load piston-cylinder is initially at 0.1 m3 , 22°C, and 100 kPa. The cylinder is then placed in a hot water bath at 100°C where the air begins absorbing eat at a constant rate of 0.5 kW. After some time it is observed that the emperature has remained relatively constant, however the volume has doubled. Determine the amount of time (seconds) that has past.

Air contained in a variable-load
piston-cylinder is initially at 0.1 m3,
22°C, and 100 kPa. The cylinder is
then placed in a hot water bath at
100°C where the air begins absorbing
heat at a constant rate of 0.5 kW. After some time it is observed that the
temperature has remained relatively constant, however the volume has
doubled. Determine the amount of time (seconds) that has past.
Answer: At = 13.86 seconds
please show steps.
