Helium gas weighs 0.40 g in a 2.0 L flask.
What will happen to the helium's entropy if it is evacuated into a bigger container while the temperature is kept constant?
Select your answer
A
As the gas becomes more organized in the larger flask, it will decrease.
B
As long as there are the same number of helium molecules, it will not alter.
C
As the gas molecules get more spread in the bigger flask, it will increase.
D
It will fall because there will be fewer collisions between the molecules and the edges of the larger flask than there were in the smaller flask.
