Answer :
Final answer:
Wine service is complete when the wine is tasted and approved by the guests. Breakage of a bottle through hydraulic shock can occur when a cork is pounded directly into liquid due to incompressibility, which doesn't happen when there's air since air can absorb the impact. the correct option is c) The wine service is truly finished when the guests have tasted and approved the wine.
Explanation:
Wine service completion:
The wine service is truly finished when the guests have tasted and approved the bottle of wine, which makes option (c) the correct choice.
When a cork is forcefully driven into a wine bottle filled with liquid to the brim, the bottle can break due to a physical phenomenon known as hydraulic shock. This occurs because liquids are incompressible, meaning they cannot absorb the energy from the impact like air can.
On the other hand, if there is air between the cork and liquid, the air acts as a cushion, compressing under the force and absorbing the impact. This does not create the same sudden pressure increase, so the bottle is much less likely to break. In summary, the distinction between air's compressibility and liquid's incompressibility is key to understanding why hydraulic shock occurs and can lead to breakage.
