Concept At constant temperature, gas solubility S in a liquid: S = kH·P (partial pressure). This is Henry’s law. Pitfalls Do not confuse with Boyle’s (P–V), Charles’s (V–T), or Raoult’s (solution vapor pressure) laws. Final Answer Henry’s law.

Difficulty: Easy

Boyle’s law
Raoult’s law
Henry’s law
Charles’s law
Dalton’s law

Correct Answer: Henry’s law

Explanation:

Concept

At constant temperature, gas solubility S in a liquid: S = k_H·P (partial pressure). This is Henry’s law.

Pitfalls
Do not confuse with Boyle’s (P–V), Charles’s (V–T), or Raoult’s (solution vapor pressure) laws.

Final Answer
Henry’s law.
