Why can the solubility of gases be higher in deep seawater?
Answer and explanation
Correct answer: Because pressure is higher
Water pressure increases with depth because a deeper point supports the weight of more water above it. For a gas in contact with the water, higher pressure generally favours dissolution and can increase its solubility, according to the pressure-solubility relation. This is why pressure is the best answer. Light, absence of salt, and solid water are not valid explanations for ordinary deep seawater.
