Pls .

for a gas in an enclosed container, if i want to maintain a certain volume of the container and i change the pressure of the gas, what else needs to change?

a. number of moles of gas
b. temperature
c. all of the above

C

Explanation:

The volume will stay the same. You are using

P*V = n * R * T

n is the number of moles. You can change that. Increase moles you increase Pressure.

T is the temperature in oK increase temperature and you increase the presure.

R is a constant just as V is. There is no change in either of them.

Therefore the answer is C Both of the above.

it's c (engineer's do their work with mechanical stuff not on any living being)
