Salt water has a higher boiling point than pure water. This means that the water gets a little hotter before coming off as steam; if the boiling point is reached, the food is cooking in water that is a little hotter than 100 degrees Celsius. The difference isn't really large, and it depends on the amount of salt in the water.
On the food
Yes, because saline water has low freezing point as compare to distilled water or pure water.
because of salt content water is saline
Yes, oil cooks food faster than water because oil has a higher heat capacity and can reach higher temperatures than water. This allows for faster heat transfer and more efficient cooking.
No, steel is denser than saline water, so a steel pin would sink in saline water.
Salt water contains a higher concentration of ions than less saline water, which makes it a better conductor of electricity.
Sliced potatoes would cook faster because there is more surface area to absorb the heat
The term "saline" just means salty. A saline solution is water with salt in it. (This is not necessarily table salt, NaCl, but can be other salts as well.)
Spaghetti will cook faster in salt water compared to plain water because the salt increases the boiling point of the water, allowing it to reach a higher temperature more quickly. This results in faster cooking times for the pasta.
Not sure what you are using saline solution for but i would say that saline solution is steril and water is not.
Approximately 97% of the total water on Earth is saline, found in oceans and seas. This saline water is not suitable for drinking or irrigation without desalination processes.
Saline is not a compound or an element; it is a solution of salt (sodium chloride) dissolved in water.
