Gases in Liquids - Henrys Law

The video tutorial explains the behavior of carbon dioxide in soda bottles. When a soda bottle is opened, carbon dioxide escapes due to differences in solubility under varying pressures. An equilibrium exists between gaseous and liquid carbon dioxide under pressure. Henry's Law is introduced, explaining that the solubility of a gas in a liquid is directly proportional to the partial pressure of the gas above the liquid.

What causes carbon dioxide to escape from a soda bottle when it is opened?

• The bottle is shaken vigorously.

• The pressure inside the bottle decreases.

• The soda is poured into a glass.

• The temperature inside the bottle increases.

What happens to the solubility of carbon dioxide in a soda bottle when it is opened?

• It increases due to higher pressure.

• It decreases due to lower pressure.

• It remains the same.

• It depends on the temperature.

What is the main factor that maintains the equilibrium between gaseous and liquid carbon dioxide in a soda bottle?

• Temperature

• Pressure

• Volume of the bottle

• Amount of sugar in the soda

According to Henry's Law, what is directly proportional to the concentration of gas dissolved in a liquid?

• The type of liquid used

• The temperature of the liquid

• The volume of the liquid

• The partial pressure of the gas above the liquid

Which scientist is associated with the law that relates gas pressure to solubility in a liquid?

• Avogadro

• Charles

• Boyle

• Henry
