If the amount of gas is decreased and the temperature and pressure stay constant, what will be the effect on its volume?
The volume will increase.
The volume will decrease.
The volume will remain the same.
The volume will be reduced to zero.
pv=nRT
v=nR (T/P)
so if n decreases, v decresases if T/P is constant
LOL
Use head, or if that fails use formula for perfect gas
P V = n R T
or
V = n R T/P
if T P and R are the same
V = n * constant
if you decrease n, you decrease V
half the molecules will fit in a half size bottle :)
Heads are sometimes hard to come by.
If the amount of gas is decreased while the temperature and pressure remain constant, the effect on its volume can be determined using Boyle's Law. Boyle's Law states that at a constant temperature, the pressure and volume of a gas are inversely proportional. This means that as the amount of gas decreases, the volume will also decrease. Therefore, the correct answer is:
The volume will decrease.
