Does it use less electricity to boil a cup of water in a microwave oven or a kettle?
Jondov
It probably Depends on the amount of water you need to boil. A small amount of water, such as the cup suggested in the question, is probably much more efficient to heat in the microwave, since it's energy is specifically targeted at the rotational energy of water molecules. Be careful of superheating. This is when the water actually heats higher than boiling point but does not bubble. Any "shock" to the system, such as putting in a spoon, will cause the water to bubble suddenly. The risk of superheating increases the cleaner the water is. Distilled water will superheat almost every time, while tap water will usually not, due to minerals that naturally occur in most water.

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.
What temp does a kettle need to be to cause evaporation?
the temperature that is needed to boil water is 100 degrees Celsius or over.
What is the fastest way to boil water in the kitchen?
Turn the burner on high. Get two small pots and put the desired amount of water (split in two) into them. Then put lids on them. It also helps to put something with rough edges so the vapor bubbles can cling to the new surface. It works faster if your are on a mountain or somewhere where there is low air pressure. And, since we all know how time goes so slow when we wait for it to pass, don't sit and watch it.
How much energy is used to boil a kettle once?
The amount of electricity it would take to boil a kettle would be phenomenal, regardless of whether the kettle is made from metal or plastic. I suggest instead you try boiling the water inside the kettle first.
The container where you can put the water in and that container can use electricity to boil the water and shut down automatically when the water is boiled?
Sounds like an automatic kettle to me. will the water that is in the container will start boil because of the atoms that is spreading out.
What is kettle's efficiency?
Kettle efficiency refers to how effectively a kettle can convert electrical energy into heat energy to boil water. A kettle's efficiency can be influenced by factors such as the material of the kettle, its insulation, and the design of the heating element. Kettles with higher efficiency tend to boil water faster and use less electricity.
Vessels for boil tea?
To boil the water, most commonly used is a tea pot. Otherwise, you could use a small pot, and some people put a mug full of water into a microwave to boil, too.
