Which of the following statements is true regarding gas absorption according to Henry's law?

Henry's law states that the amount of a gas that will dissolve in a liquid at a given temperature is proportional to the partial pressure of that gas above the liquid. This principle indicates that when the partial pressure of a gas increases, more gas molecules will enter the liquid phase, thus increasing the rate at which gas absorption occurs. This relationship is linear, meaning that as pressure continues to rise, the amount of gas absorbed continues to increase accordingly.

This is a fundamental concept in areas such as underwater diving and rescue operations, where understanding the behavior of gases under different pressures is critical for preventing issues like decompression sickness. In practical scenarios, this means that if a diver ascends quickly from a depth where there is high pressure, the rapid decrease in pressure can lead to nitrogen gas coming out of solution too quickly, which is a direct application of Henry's law in undersea environments.

Therefore, the correct choice highlights the direct correlation between gas absorption and the increase in partial pressure, making it an essential concept in the comprehension of gas behavior in liquids.
