IN eCampus-PHYS 2110-x Sapling Learning Jump A9inder win?move ble piste.nsde Cholds a voann of arof 0.105 mat a pressure of 255 kPa The pison inside moves, changing the volume to 0.90malthough the emperature of the gns does not change (See the iagam at right.) Pat A This gas prensa WX?d be dttled as what? (POhe comect answer ?Anadabatic process O An anachronistic process ?Aniiodote process Pwt B Consider any work or heat fow ocorng wth tus procesa (Pek?the statemeres that are corre 2) There must be heat entering the gas sonehow There must be heat leaving the gas somehow There is no hest entering or lesving the gas Something is performing work on the gas The gas is perfonming work somehow ? Then ro won nded in his process. O Type here to searchExplanation / Answer
A)
as the temperature is constant, this is an isothermal process
B)
There must be heat entering the gas.
The gas is performing work.
The internal energy of the gas remains unchanged during this process.
C)
Now, for the final pressure
Pi * vi = Pf * Vf
25.5 x 10^3 x 0.105 = Pf x 0.906
Pf = 2955.30 Pa
Pf = 29.55 x 10^2 Pa
