5-120 Consider a 20-L evacuated rigid bottle that is surrounded by the atmosphere at 100 kPa and 27°C. A valve at the neck of the bottle is now opened and the atmospheric air is allowed to flow into the bottle. The air trapped in the bottle eventually reaches thermal equilibrium with the atmosphere as a result of heat transfer through the wall of the bottle. The valve remains open during the process so that the trapped air also reaches mechanical equilibrium with the atmosphere. Determine the net heat trans through the wall of the bottle during this filling process. Answer:= 2.0 kJ Air 20 L evacuated FIGURE P5-120 100 kPa 27°C

Select the correct statements regarding moment and torque.  (Select 3) Moment and Torque are two different phenomena, hence SI- units are different   Generally Moment is used when there is no rotation, while torque is used when there is rotation.   Moment and torque are very similar concepts and are sometimes interchangeable   Moment and Torque are calculated by force multiplied by its distance to the reference point.

Need help on all questions. Please include all units, steps to the problem and information such as its direction or if it is in compression or tension. Thx.
