Yes. If you place pasta in already boiling water it will be quicker, because usually you time the cooking of pasta from when the water begins to boil.
Because salt raises the boiling point of water...which is why you cook things like eggs and pasta in salted water: because of this effect, the water gets hotter and the food gets done faster.
Fresh water evaporates faster because the dissolved salts in salt water raise the boiling point by strengthening the intermolecular bonds water molecules have with each other. It's why you salt pasta water--to increasing the boiling point of the water so you can cook it at a higher temperature (and season the pasta). Adding salts also lower the freezing point of water, which is why people salt roads before snow.
So the noodles don't stick together!
It is a physical change: the water is absorbed into the sponge-like pasta. The elements and compounds of the flour and water are not changed, and you could even dry the pasta out again (with a probable loss of quality).
Pasta needs to cook in rapidly boiling water, so a double boiler won't work that well for cooking pasta.
If you add pasta to cold water, and then bring it to a boil, the starches will begin to dissolve. This will cause a very sticky surface on the pasta, and it will clump together. By adding the pasta to boiling water, the surface starches cook right away.

of course, Ive done many times
The boiling point of any liquid is dependent upon the pressure of the atmosphere above the liquid therefore water boils at a lower temperature at higher altitudes. Because of this, the pasta takes longer to cook in the cooler boiling water.
No less than 1 quart.

If you add any type of pasta into a pot of cold water then boil this will cause starches to dissolve the pasta surface, in a result the pasta will stick. When the water is boiled at its highest temperature, the pasta will cook to perfection and faster.
when you cook them by themselves to later add other ingredients such as meat, by the time the water starts boiling the pasta is cooked.
Let the pasta come to room temperature in a pot of water, gently separate it and have a pot of boiling water with half a teaspoon of olive oil ready to cook it in. Lower it into the boiling water for 8 minutes gently stirring occasionally.
Adding a little salt to the boiling water gives pasta a little taste or flavor.
