A gas becomes more soluble in a liquid when the pressue of the system is decreased.
A. True
B. False
B. False
B. False
When the pressure of a system is decreased, the solubility of a gas in a liquid typically decreases. According to Henry's law, the solubility of a gas is directly proportional to the partial pressure of the gas above the liquid. Therefore, when the pressure is lowered, the partial pressure of the gas decreases, reducing its solubility in the liquid.
B. False
Explanation: The statement is incorrect. In fact, according to Henry's law, the solubility of a gas in a liquid is directly proportional to the partial pressure of the gas above the liquid. So, as the pressure of the system is increased, the gas becomes more soluble in the liquid, and as the pressure is decreased, the gas becomes less soluble.
