Answer:
Explanation:
The Ideal Gas Law states that PV=nRT.
Rearrange that into P/n=RT/V.
In this case, the cylinder is rigid so the volume, V, does not change.
Temperature does not change either.
Out of 450 grams of gas, 150 grams leak out. So only 450-150 = 300 grams is left.
n is number of moles which is dependent on mass:
n1/n2 = 450/300 = 3/2
P1/n1 = RT/V = P2/n2
P2 = P1/n1*n2
= 7.2/3*2
= 4.8 atmosphere
Answer:
The solid will sublime into a gas
Explanation:
In the graph in the attachment
Y-axis represents pressure in mm of Hg
X- axis represents temperature in degree Celsius
The graph show the triple point of water.
Clearly, the sample will go from solid to vapor directly, no liquid involved (pink line is there to show that this is below triple point)
So
expect sublimation
The solid will sublime into a gas.
