What advantage is there to adding salt to cooking water?
and what conditions are necessary for ideal carbonation of a beverage?
please help

So for the first one, would the answer be that salt makes the water boil at a higher temperature because the salt molecules weigh down the water molecules and restrict their movement? This is what it says on the websites, but I am not quite sure I understand it.
All I got from the third website, for the second question, is that CO2 must be dissolved under pressure in a liquid.
salt does not help water boil faster at all. it actually makes water boil slower. with the salt acting as a solute, the boiling point of salt water is higher than just water alone. However, the salt water will cause the noodles to cook faster, since it is already at a higher temp.
and it tastes better. (:
You're partially correct about the first question regarding the advantage of adding salt to cooking water. Salt does indeed increase the boiling point of water, but it doesn't necessarily make the water boil at a higher temperature because the salt molecules weigh down the water molecules and restrict their movement.
When you add salt to water, the salt molecules dissolve and form ions, creating a solution that has a higher boiling point than pure water. This means that it requires higher heat energy to make the water reach its boiling point. However, it doesn't significantly increase the boiling point, but rather just slightly raises it.
The advantage of adding salt to cooking water is that it enhances the flavor of the food that is being cooked in it. Salt penetrates the food and enhances its natural taste, making it more flavorful. Additionally, salt also helps to season the food evenly, resulting in a more balanced flavor.
As for the second question about the ideal conditions for carbonation, you are correct that carbon dioxide (CO2) needs to be dissolved under pressure in a liquid for carbonation to occur. Carbonation is the process of dissolving carbon dioxide gas into a liquid, usually water, to produce carbonated beverages like soda.
To achieve ideal carbonation, there are a few factors to consider. First, the liquid (usually water) needs to be chilled before carbonation. Cooler temperatures allow for greater solubility of carbon dioxide in the liquid.
Next, the liquid needs to be pressurized with carbon dioxide gas. This is commonly done by carbonation machines or carbonation tanks used in beverage production. The pressure helps the gas dissolve into the liquid more effectively.
Lastly, once the liquid is carbonated, it is important to maintain the pressure to keep the carbon dioxide dissolved. This is why carbonated beverages are stored in sealed containers, such as bottles or cans, to retain the carbonation.
I hope this helps clarify the answers to your questions!
