A gas becomes more soluble in a liquid when the pressue of the system is decreased.
True

False
False.
A gas becomes more soluble in a liquid when the pressure of the system is increased, not decreased. 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. Therefore, increasing the pressure increases the solubility of the gas in the liquid.
True.
This is known as Henry's Law, which states that the solubility of a gas in a liquid is directly proportional to the partial pressure of the gas above the liquid. According to Henry's Law, as the pressure of the gas above the liquid is decreased, the solubility of the gas in the liquid also decreases. Conversely, increasing the pressure increases the solubility. This relationship is often observed when opening a carbonated beverage - the decrease in pressure causes the carbon dioxide gas to be released as bubbles.
