How do specific word choices develop
the history teacher's character

idk i just need the points

i don't really know the circumstances. i personally think not due to it not being fair for all parties and how hated i'd become if i thought it was a good thing.

the gas pressure p, gas volume v, and gas temperature t are given in the formula:   pv=nrt,

r is the gas constant, and n is the number of gas moles.

if the container is cooled and remains under atmospheric pressure, where r is a constant that does not change, the volume of the container remains the same, the conclusion is drawn that, with all other values ​​unchanged, the number of gas moles n, is decreases.

the right answer is a.
