The diagram represents three vessels that contain the same amount of Argon gas, but with different temperatures and volumes.?
Assuming ideal gas behaviour, nominate which one or more of the vessels has gas with:
(a) the highest pressure
(b) the highest average kinetic energy
chose from:
I
II
III
I & II
I & III
all 3
回答 (3)
(a)
Combined gas law: PV/T = constant
Then, P = constant × (T/V)
Hence, P ∝ T/V
The higher the temperature and the smaller the volume, the higher the pressure is.
I and II have the highest temperature, while I and III have the smaller volume.
Hence, I has the greatest pressure.
The answer: I
====
(b)
The higher the temperature, the highest average kinetic energy of the gases particles is.
I and II have the highest temperature. Hence, I and II have the greatest average kinetic energy.
The answer: I & II
a)
Supposing containers I and III have the same volume, I has the highest pressure.
b)
I & II have the highest average KE
