A 1-L soda bottle contains dissolved carbon dioxide gas. Which bottle would have the highest concentration of dissolved gas? a bottle that is sealed a bottle that was opened 1 minute ago a bottle that was opened 1 hour ago a bottle that was opened 1 day ago
Answers
Explanation:
When the pressure is released by opening the soda container, the liquid cannot hold as much carbon dioxide, so the excess bubbles out of the solution. If the soda is left open, additional carbon dioxide will slowly escape into the air. Under warm conditions, the carbon dioxide leaves the solution faster.
The highest concentration of dissolved gas is present in a bottle that is sealed.
Explanation:
It is known that when a system is closed then there will occur no change of matter and energy between the system and surrounding. Therefore, when carbon dioxide gas is dissolved in 1 L of soda bottle and if this system is closed then no exchange of matter and energy will take place.
Hence, the carbon dioxide gas will remain dissolved in the system (closed bottle). As a result, it will have maximum concentration in a sealed bottle. But when the system is opened then gas will disappear into its surroundings by leaving the system.
As a result, in an open system there will be low concentration of carbon dioxide gas.
