Question

Why does a newly opened can of warm soda have less carbonation than a newly opened can of cold soda?


A.At a constant pressure, gases are less soluble in liquids at higher temperatures.

B.At a constant pressure, gases are more soluble in liquids at higher temperatures.

C.Liquids expand at higher temperatures, leaving less room for gases.

D.Liquids contract at higher temperatures, making more room for gases.

Answer 1

Answer is: A.At a constant pressure, gases are less soluble in liquids at higher temperatures. Carbonated drinks lose their fizz at higher temperatures (gases move faster anf have higher energy) and when the carbonated soda is colder (gases move slowe and have less energy), the dissolved carbon dioxide (CO₂) is more soluble and fizzes more when opened.
