Boyle's law, which summarizes these observations, states that: the volume of a certain amount of gas, which is maintained at a constant temperature, is inversely proportional to the pressure exerted, which is summarized in the following expression:
P.V = constant or P = 1 / V
Example:
An inflated balloon with a volume of 0.55L at sea level (1.0 atm) is allowed to rise to a height of 6.5 km, where the pressure is about 0.40 atm.
Assuming that the temperature remains constant, what is the final volume of the balloon?
Reasoning and solution:
Note that the number of moles and the temperature of the gas remain constant, so Boyle's law is used. From the equation:
P1V1 = P2 V2
Where P1 = 1 atm, V1 = 0.55L and P2 = 0.40 atm, as well
V2 = V1 x (P1 / P2) = 0.55 L x (1 atm / 0.40 atm) = 1.4 L
When the pressure is reduced (at a constant temperature), the volume increases. The final volume is greater than the initial volume, so the answer is reasonable.
The size of the rocks
Explanation:
One key factor in the rate of chemical weathering is the size of the rocks. The rate of chemical weathering like other chemical reaction depends on the size of the rocks.
- Chemical weathering is the decomposition and decay of rocks.
- In chemical weathering, a rock unit undergoes a chemical change.
- For an effective chemical weathering of a rock, physical disintegration of a rock piece must have occurred first.
- The surface area exposed proportionally affects the rate of chemical weathering.
- Smaller chunks of rocks have a large surface area and they are weathered faster.
