No, water that is covered does not boil faster. Covering the pot can actually trap heat and make the water boil slower.
== ==
A small amount of water will reach it's boiling point sooner than a large amount of water. It will not boil faster.
no it does not
yes
Covering water can make it boil faster because it traps the heat and prevents it from escaping, increasing the temperature of the water more quickly.
no
makes it boil faster
yes
there are already bubbles in it
It does NOT boil faster than water. It has higher boiling point AND lower freezing point. - Antifreeze boils at about 197 c.
No, salt water does not boil faster than water with pepper. Adding salt or pepper to water may change its boiling point slightly, but the difference is not significant enough to affect the time it takes to boil.
