The video tutorial discusses the factors affecting the solubility of gases in liquids. It covers four main factors: the nature of the gas and solvent, the effect of temperature, the addition of soluble salt, and the effect of pressure. Each factor is explained with examples, such as the solubility of carbon dioxide in water and the impact of temperature on gas expansion. The tutorial also highlights how adding salt can decrease gas solubility and how pressure can increase it. The video concludes with a call to action for viewers to subscribe and share.

Which of the following is NOT a factor affecting the solubility of gases in liquids?

• Nature of gas and solvent

• Effect of temperature

• Color of the gas

• Effect of pressure

Why is carbon dioxide more soluble in water compared to oxygen?

• Oxygen is a polar molecule

• Carbon dioxide and water are both polar

• Water is a non-polar solvent

• Carbon dioxide is a non-polar molecule

What happens to the solubility of a gas in a liquid as the temperature increases?

• It remains the same

• It decreases

• It doubles

• It increases

What is the effect of boiling water on the gases dissolved in it?

• Gases dissolve more

• Gases remain unchanged

• Gases evaporate

• Gases turn into solids

What is observed when salt is added to a carbonated beverage?

• The beverage becomes sweeter

• The beverage freezes

• The beverage changes color

• Effervescence occurs

How does the addition of a soluble salt affect the solubility of gases in a liquid?

• Doubles the solubility

• Has no effect

• Decreases solubility

• Increases solubility

What happens when you open a carbonated beverage bottle?

• The liquid solidifies

• The gas pressure increases

• The gas escapes

• The liquid evaporates

How does increasing pressure affect the solubility of gases in liquids?

• Turns gas into liquid

• Has no effect

• Decreases solubility

• Increases solubility
