Divers who go to great depths in the ocean experience large differences in pressure between the surface and their final destinations below the surface. At times, they have to avoid quick changes in pressure because of the effects on the solubility of nitrogen in their blood. If the solubility decreases quickly, then gas bubbles can form in the person's blood, causing a dangerous condition called "the bends."

In one or two sentences, state whether you would expect the condition to be a greater hazard for divers as they dive down or as they return to the surface. Then, explain your prediction in terms of the solubility of gases in liquids at different pressures.

The condition of "the bends" would be a greater hazard for divers as they return to the surface. This is because as the pressure decreases during ascent, the solubility of nitrogen in their blood decreases, leading to the formation of gas bubbles.

I would expect the condition known as "the bends" to be a greater hazard for divers as they return to the surface. This is because as divers ascend, the pressure decreases, causing the solubility of nitrogen in their blood to decrease rapidly. This leads to the formation of gas bubbles, which can be dangerous.

I would expect the condition to be a greater hazard for divers as they return to the surface. This is because as divers ascend, the pressure decreases, causing the solubility of nitrogen (and other gases) in their blood to decrease. If the ascent is too rapid, the nitrogen bubbles out of the blood, leading to the formation of gas bubbles and potentially causing the bends.
