Aflask containing argon gas is connected to an closed-ended mercury manometer. the closed end is under vacuum. if the mercury level in the closed arm is 230. mm above that in the arm connected to the flask, what is the argon pressure, in torr?

230 torr

Explanation:

Given that

P = 230 mm of Hg

If argon gas and mercury is in equilibrium position then the pressure on the both side will be same .

As we know that

1 torr = 1 mm of Hg

So the pressure of the argon will be 230 torr .

Unit conversion

1 torr = 1 mm of Hg

1 bar = 100 KPa = 10⁵ Pa =  10⁵ N/m² = 0.1 MPa = 0.1 x 10⁶ Pa

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.
