A piston-cylinder assembly contains nitrogen (N2), initially at 2.5 bar, 300 K, and a volume of 2 m3 . The nitrogen undergoes a process to a state where the pressure is 1 bar, during which the pressure-volume relationship is pV = constant. Assuming ideal gas behavior for the nitrogen, determine the mass of the nitrogen, in kg, and the work and heat transfer, each in kJ. Kinetic and potential energy effects can be neglected

sleep paralysis is a parasomnia, events associated with sleep.

sleep paralysis happens when you are in the middle of waking up or falling asleep. it is the feeling of being conscious but unable to move. it definitely involves hallucinations.

i had a friend that had sleep paralysis and he told me a story one time where he was laying in bed and he couldn't move his body no matter how hard he tried and there was someone standing in the corner of his room coming towards him. he couldn't move and you can't "wake up" because you are already conscious. sometimes sleep paralysis can be triggered by frequent waking up during the night based off of multiple trips to the bathroom, or if you had ever been abused, sleep paralysis can start happening from things like that.

that would be because of both gravity and friction. so     c
