Part A
Consider what you have learned about subject and theme in literature. What is the subject, and what is one central theme in this story? How does the author introduce and develop this theme throughout the text?

who r u questiiiobnn

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.
