Do you prefer to drink a carbonated beverage or a cup of coffee? Either way, you are familiar with the sound produced when opening a carbonated drink or opening a can of coffee grounds. The hissing sounds produced are different. 1. Explain thoroughly the cause of the hissing sound when a carbonated beverage is open using the concepts learned about gases. 2. Explain thoroughly the cause of the hissing sound when a can of coffee grounds is open using the concepts learned about gases. 3. Why are the two sounds different? Explain thoroughly.

Question

Accepted Answer

∻Solution∻ ‖ 1 ⋮ **Explain the cause of the hissing sound when a carbonated beverage is opened**: When a carbonated beverage is sealed, carbon dioxide ($CO_2$) is dissolved in the liquid under high pressure. Upon opening, the pressure is released, causing the $CO_2$ to rapidly escape from the liquid into the air, producing the characteristic hissing sound. This is due to the gas laws, particularly Henry's Law, which states that the amount of gas dissolved in a liquid is proportional to the pressure of the gas above the liquid. ‖ ‖ 2 ⋮ **Explain the cause of the hissing sound when a can of coffee grounds is opened**: The hissing sound when opening a can of coffee grounds is due to the release of air that was trapped inside the can during packaging. This air is at a slightly higher pressure than the atmospheric pressure outside the can. When the can is opened, the pressure equalizes, causing the air to rush out and produce a hissing sound. ‖ ‖ 3 ⋮ **Explain why the two sounds are different**: The difference in the sounds is due to the nature of the gases involved and the pressure differences. In the case of the carbonated beverage, the $CO_2$ gas is dissolved in the liquid and escapes rapidly when the pressure is released, creating a sharper and more intense hissing sound. In contrast, the air in the coffee can is simply trapped and released, resulting in a softer and less intense hissing sound. ‖ ∻Answer∻ ⚹ The hissing sound from a carbonated beverage is due to the rapid escape of dissolved $CO_2$ gas when the pressure is released, while the hissing sound from a can of coffee grounds is due to the release of trapped air. The difference in sounds is due to the nature and pressure of the gases involved. ⚹ ∻Key Concept∻ ⚹ Gas laws and pressure differences ⚹ ∻Explanation∻ ⚹ The hissing sound from a carbonated beverage is caused by the rapid escape of $CO_2$ gas due to pressure release, while the hissing sound from a can of coffee grounds is due to the release of trapped air.
