Increasing Partial Pressure of Gas Above a Solution

What is the term used to describe the mutual solubility of components in liquid-liquid systems?

Miscibility (correct)
Adhesiveness
Cohesiveness
Solubilization

What does Henry's law state?

The concentration of dissolved gas is directly proportional to the partial pressure of the gas. (correct)
The concentration of dissolved gas is inversely proportional to the partial pressure of the gas.
The concentration of dissolved gas is equal to the total pressure above the solution.
The concentration of dissolved gas is not affected by the partial pressure of the gas.

In completely miscible liquids, what is the relationship between adhesive and cohesive forces?

Adhesive forces = cohesive forces
Adhesive forces and cohesive forces are irrelevant
Adhesive forces > cohesive forces (correct)
Adhesive forces < cohesive forces
