Final answer:
A wine bottle can break when a cork is pounded directly against the liquid due to hydraulic shock, but it's unlikely to break if there is air between the cork and the liquid because air can compress and absorb the impact.a) True
Step-by-step explanation:
When a cork is pounded into a wine bottle filled completely with liquid, the force of the pounding is transmitted through the incompressible liquid to the glass, causing it to break under pressure. This phenomenon is known as hydraulic shock, where the liquid effectively transmits the force applied on the cork to the bottle's wall or base, potentially causing a fracture if the structural integrity of the glass is compromised or the force is strong enough.
Conversely, if there is air between the cork and the liquid, the bottle typically will not break. This is because air is compressible and acts as a cushion, absorbing and dissipating the force of the impact, which reduces the pressure exerted on the glass walls or bottom of the bottle.The statement is false. When pouring wine into a decanter, it is important to stop pouring once the deposit can be seen near the neck of the bottle. The deposit, also known as sediment, forms naturally in wine over time. It consists of grape solids, tannins, and other compounds that settle at the bottom of the bottle. By pouring the wine carefully and stopping before the deposit is disturbed, it allows the wine to be decanted without agitating the sediment and pouring it into the glass.
