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!

∙ 15y agono a lid will actually help it boil faster but should be taken off after coming to a boil so it does not bubble over
Wiki User
∙ 15y agoWater boils faster with a cover on it because more heat stays inside the pan.

∙ 6y agoNo, it is inverse.

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.
What is the source of the condensed water?
When water molecules get to a certain temperature, they change into their gas state (evaporation). Condensation occurs when the evaporated water hits something cool, and it reverts back to its liquid state. This is why if you boil water and then put a lid over it, condensation gathers in the top of the lid. Also condensed water can be dew drops. They are purified.
How does a Crofton Electric Water Kettle work?
There is a heating element in the kettle. As the water boils, the inner temperature of the kettle rises. Once the boiling temperature is reached, a small thermostat is triggered which turns the kettle off, so as to not boil continually. This thermostat works optimally with the lid on the kettle fully closed, if the lid is not fully closed, it does not switch the kettle off as quickly.
A pot of water on a hot stove begins to boil rapidly a glass lid is placed on the pot water droplets begin forming on the inside of the lid what happened?
Condensation. The air on the outside of the pan will be cooler than the air inside the pan leading to the lid being cooler (maybe only slightly) than the steam inside the pan. When the steam hits the cooler lid it will cool down and condense to form the water droplets.
Why water boils quicker on mountains?
boiling temperature remains same. air temperature varies . in mountains air temperature is lower. as surrounding temperature is lower water boils faster.,.or in other words heat transfer occurs faster due to difffernce in temperature. sorry to disagree the higher you go the lower the boiling point due to atmospheric pressure ex.. on Everest they cannot boil water hot enough to make tea My approach aside from above statements is: since boiling occurs when the pressure applied by the high kinetic energy molecules of water becomes same as that of atmospheric pressure. And since the pressure at mountains is low therefore boling temperature is lower in the same way. A good example is of pressure cooker, due to steam tightness, high pressure is generated in pressure cookers which thus increases the temperature of water inside because the boiling point of water is increased. Thus cooking food at high temperatures in few minutes. hope that the question is anwered. regards!:-)
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.
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.

Chandra helped his mother to boil some water using a kettle After a while he observed white mist escaping from the lid of the kettle The white mist is a condensation process taking place Why?
The mist escapes the kettle because of the high pressure. Outside, the temperature and pressure are much lower (room temperature and 1 ATM pressure), so water condenses again since it's liquid in such conditions.
The process that turns sea water into fresh water is?
When you boil salt water, the salt will be left behind as a solid. You can collect the water by distillation. For example, if you boil the salt water in a pot with a lid, and leave the lid at an angle, the evaporated water will collect there and fall off - so you can collect it.Desalination is a process that removes some of the salt from water - making sea water drinkable.
Why are jar lids immersed in water for a few seconds?
Short answer: This is normally done when a lid is too tight to unscrew. Placing the lid in warm or hot water loosens the lid a little so someone can get to the contents of the jar easier. Long answer: Metal reacts to heat at a lower temperature than glass does. When a metal lid is placed in warm or hot water, the lid expands outwardly from its center. This will cause the lid to loosen its grip on the jar making it easier for a user to unscrew the lid. It's simple science and a neat trick.
Why do you boil lids before canning when they will be boiled during the process anyway?
Sometimes you boil the lids and sometimes you don't. If you are canning with either a hot water bath or in a pressure cooker, you do not need to boil the lids. If you are canning something that is put into the jar hot and is not going to be processed in the the bath or pressure cooker, you boil the lid to soften the rubber in the lid that forms the seal.
What is an example of evporation?
When you boil water and then later come back, and take the lid off the pot and steam comes out, then you have evaporation
