The solubility of a gas in a liquid is affected by pressure according to Henry's Law, which states that the amount of gas that dissolves in a liquid is directly proportional to the partial pressure of that gas above the liquid. Thus, the correct response is:
Increased pressure = Increased solubility
To summarize:
- Increased pressure results in increased solubility of a gas in a liquid.
- Decreased pressure results in decreased solubility of a gas in a liquid.
- This relationship is quantitatively described by Henry's Law, which highlights the effect of gas pressure on solubility.
