Henry's law states that when a gas is in contact with a liquid, that gas will dissolve in the liquid in proportion to its partial pressure.
A
False
B
True
Verified step by step guidance1
Understand the concept of Henry's Law: It states that the amount of gas that dissolves in a liquid is directly proportional to the partial pressure of the gas above the liquid.
Recognize that Henry's Law is applicable in various physiological contexts, such as the exchange of gases in the lungs where oxygen and carbon dioxide dissolve in blood.
Consider the implications of Henry's Law in real-life scenarios, such as how increased pressure can lead to more gas dissolving in a liquid, which is relevant in diving and hyperbaric medicine.
Reflect on the statement given in the problem: 'Henry's law states that when a gas is in contact with a liquid, that gas will dissolve in the liquid in proportion to its partial pressure.'
Conclude that the statement is indeed true based on the definition and applications of Henry's Law, as it accurately describes the relationship between gas pressure and solubility in a liquid.
