Yes, but not very much. The purpose of the lid is to insulate the water or whatever else is inside the pot. As it does this, though the lid also increases the air pressure pressure slightly. Water boils at higher temperatures under higher pressures. So there is in effect a competition between the insulation effect and the pressure effect. I did an experiment on my kitchen stove and found that water boils very slightly faster with the lid on. This experiment has led me to conclude that from a time saving perspective, it makes very little difference whether you put the lid on or not. From an environmental perspective, however, it is much worse for global warming and resource depletion if billions of people are boiling water without the lid.
So: PUT THE LID ON!

∙ 15y agowater boils faster with the lid on because the heat gathers in the pot making the water boil.

∙ 15y agoYes, it does. energy will escape from an open pot.

Does water evaporate faster with lid or no lid?
Less heat will escape with the lid on. As the pressure inside the pan increases, the liquid boils faster - so both aspects combined makes the water to boil faster and save energy. Without a lid, the water won't boil as fast or as quickly, and more energy will be used.
How can colourless the coloured water?
Boil it with a cup and a lid on. Boil it for 10 minutes and open the lid. The water droplets under the lid will be colourless
Why puttung lid on saucepan makes the water in it comes to boil come to boil more quickly?
Putting a lid on the pan makes the water boil quicker because the heat is trapped, less is escaping, so the water's temperature has more time to increase, so it gets more hot and boils faster.
What is a false boil?
A false boil is basically a cooking "old wives tale." It was based on the assumption that placing a lid on a pot of water to boil it caused pressure to build up which caused air bubbles to be forced into the water, giving an appearance of a boil, when boiling temperature had not actually been reached. In actuality, the lid helps the water to reach the boiling point faster.
Is the boiling temperature higher or lower when you use a lid?
If the lid is tight enough to raise the pressure in the pan (as in a pressure cooker), the boiling temperature will be higher. However, if the lid just sits loosely on top, it will make the water boil sooner because not as much heat is lost and the water heats up faster.
Does a glass of water evaporate faster with a lid or without?
A glass of water evaporate faster without a lid.
Which boils first open lid or close lid?
Closed lid. It allows for the heat to build up quicker therefor making it boil faster.
Do water with salt evaporation faster with a lid on it or with out?
Faster without a lid because the lid recaptures steam and condenses it back
Does the amount of salt affect how long it takes to boil?
yes, It gets the convection current going faster and makes the water hotter. it also helps to put a lid on with the salt already in the water
Does water in a pot boil at a lower temperature if it has a lid on it?
I did a science project on how long it takes to boil water by changing variables. One of them was to add canola oil (the same as vegetable) and it ended up boiling almost a minute faster than just plain water!
What should you do to help liquids boil faster?
Use less water, keep the lid on, use a higher flame, use a thinner pot. Alternatively, use an electric kettle.
Will soup cook faster with or without lid?
It is best to cook soup very slowly, so always avoid fast boil. You can use a lid, but have it slightly lifted.
