It does that because petrol is a liquid chemical,has a lower mass per volume,or density,then the water on top so it spread out on top of the water
The bare rock will erode, once it erodes the rock will no longer be bare cause eroded sediment will cover it.
Answer:
The answer to your question is T2 = 610.9 °K
Explanation:
Data
Volume 1 = V1 = 30 cm³
Temperature 1 = T1 = 420 °K
Pressure 1 = P1 = 110 kPa
Volume 2 = V2 = 40 cm³
Temperature 2 = T2 = ?
Pressure 2 = P2 = 120 kPa
Process
To solve this problem use the combined gas law.
P1V1/T1 = P2V2/T2
-Solve for T2
T2 = P2V2T1 / P1V1
-Substitution
T2 = (120 x 40 x 420) / (110 x 30)
-Simplification
T2 = 2016000 / 3300
-Result
T2 = 610.9 °K
The numerical setup is
<span>11<span>g</span></span>CO2×1 mol CO2/44.01g CO2=0.25 mol CO2
gCO2 cancels out so it is
11 x 1 mol CO2/44.1 CO2= 0.25 mol CO2
