The pressure of a gas is 1.0 atm, the volume is 3.0 l, and the temperature is 200 k. a chemist changes one factor while keeping another constant so that the new pressure is 2.0 atm. which of the following could be the new conditions?
a. the final volume is 6.0 l, while temperature is kept constant.
b. the final temperature is 100 k, while volume is kept constant.
c. the final volume is 4.0 l, while temperature is kept constant.
d. the final temperature is 400 k, while volume is kept constant.

The answer to your question is letter: letter D

Explanation:

Data

P1 = 1 atm

V1 = 3 l

T = 200 K

V2 = 2 atm

Formula

          P1V1 = P2V2         (P1/T1) = (P2/T2)             (V1/T1) = (V2/T2)

A. The final volume is 6.0 L, while temperature is kept constant.  This answer is wrong because if the final pressure is 2 atm, then the final volume will be  1.5 l, not 6 l.

B. The final temperature is 100 K, while volume is kept constant.  This answer is incorrect, if the final pressure is 2, then the final temperature is 400°K

C. The final volume is 4.0 L, while temperature is kept constant.  This answer is incorrect, if the pressure increases, then the volumen diminishes.

D. The final temperature is 400 K, while volume is kept constant. This answer is correct, if the final pressure is 2, then the final temperature is 400°K.

D the final temperature is 400 K, while volume is kept constant.

Explanation: Took the quiz :)

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
