A2-m^3 insulated rigid tank contains 2 kg of carbon dioxide at 100 kpa. now paddle-wheel work is done on the system until the pressure in the tank rises to 150 kpa. determine the entropy change of carbon dioxide during this process. assume constant specific heats.

Two technicians are discussing the intake air temperature (iat) sensor. technician a says that the computer uses the iat sensor as a backup to the engine coolant temperature (ect) sensor. technician b says that the powertrain control module (pcm) will subtract the calculated amount of fuel if the air measures hot. who is correct

Abrake has a normal braking torque of 2.8 kip in and heat-dissipating cast-iron surfaces whose mass is 40 lbm. suppose a load is brought to rest in 8.0 s from an initial angular speed of 1600 rev/min using the normal braking torque; estimate the temperature rise of the heat dissipating surfaces.

Burgers vector is generally parallel to the dislocation line. a)-true b)-false
