Fill in the blank: A solution that contains the maximum amount of solute that can dissolve at a given temperature is called a ___ solution.

Saturated

True or False: The solubility of gases in liquids generally increases with an increase in temperature.

False. The solubility of gases in liquids generally decreases with an increase in temperature.

Describe the impact of pressure on the density of gases compared to solids.

Pressure increases gas density.

• Gas particles compress under pressure.

• Solids' density remains stable.

• Density change varies by state.

What happens to the density of a substance when it is heated, and why?

Density decreases with heating.

• Mass stays constant.

• Volume increases with heat.

• Particles expand when heated.

Fill in the blank: When an object sinks in water, it is generally because its density is ___ than that of water.

Greater

What role does the solvent play in the formation of a solution?

The solvent dissolves the solute to form a solution, determining its state and properties.

Riddle: You can find me in the air, but I am not seen. I help fish breathe but am rarely in the scene. What am I?

Dissolved oxygen.

What factors influence the solubility of gases in liquids, and how does temperature affect this solubility?

Temperature affects gas solubility.

• Higher temps reduce gas solubility.

• Pressure also influences solubility.

• Contrasts with solid solubility trends.
