After the temperature returns to the original value, compared with the starting pressure the final pressure is:
A
lower because compression always lowers pressure after it settles.
B
higher because the gas is in a smaller volume, causing more frequent wall collisions at the same average particle speed.
C
zero because particles lose motion during compression.
D
the same because the temperature returned to the original value.
