There are many factors that affect the loss of energy:
1 the resistance of the wire
2 the kettle will keep most heat in but not all heat within the kettle so more energy is lost
3 the water will evaporate out the top and that is also a cause. (they can't close it off otherwise the pressure would build and it would explode).

What is kettle scale?
Kettle scale, also known as limescale, is a hard, chalky deposit that forms inside kettles and other appliances due to the evaporation of hard water, which contains high levels of calcium and magnesium salts. Over time, these minerals accumulate and create a buildup that can affect the efficiency of the kettle and alter the taste of boiled water. Regular descaling can help maintain the kettle's performance and prolong its lifespan. Using descaling agents or natural substances like vinegar can effectively remove kettle scale.
Which parts of the electric kettle are made of good insulators of heat?
The outer part as the part you hold the kettle from to prevent injures.
What is a nonreactive kettle?
the kettle does not react
What energy does an electric kettle have?
The energy which powers a kettle ultimately comes from the Sun. While a kettle is powered by electrical energy if it is an electric kettle or gas if it is whistling kettle, the energy ultimately comes from the Sun and came to Earth as sunlight.
How much water does a kettle hold?
It depends on the size of the kettle.
How do you increase a kettle's efficiency?
To increase a kettle's efficiency, you can use a kettle that is the right size for your needs, regularly descale it to remove mineral buildup, and match the heat source to the kettle material. Additionally, keeping the kettle lid on while heating water and using an insulated kettle can help retain heat and improve efficiency.
Is it true that thermal efficiency of a diesel engine equals indicated thermal efficiency - brake thermal efficiency?
no
What is a sound physics reason for keeping a kettle polished?
Keeping a kettle polished can help prevent the formation of rust on the surface, which can affect the thermal conductivity of the material. By maintaining a smooth and polished surface, the heat transfer efficiency of the kettle can be preserved, allowing the water to heat up more quickly and evenly.
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.
What energy transformation in kettle?
In a kettle, electrical energy is transformed into thermal energy through the process of resistive heating. The heating element inside the kettle uses the electrical energy to generate heat, which raises the temperature of the water inside the kettle.
What is the energy coversions in a kettle?
In a kettle, electrical energy is converted into thermal energy by the heating element. This thermal energy then transfers to the water, raising its temperature and causing it to boil.
What form of energy does the kettle have when water in it is boiling?
it is where you say chocolate is equal to me (human) T.H ROCKS
What is the formula to calculate the thermal efficiency of an Otto cycle engine?
The formula to calculate the thermal efficiency of an Otto cycle engine is: Thermal Efficiency 1 - (1 / compression ratio)
What forms of energy does a kettle have?
A kettle has electrical energy when it is plugged in and heating up water. It also has thermal energy, as it heats up the water inside.
How thermal energy is conducted through walls of the kettle with reference to kinetic theory of matter?
Thermal energy is conducted through the walls of a kettle by the process of conduction. Within the walls of the kettle, the particles of the material vibrate and transfer energy to neighboring particles through direct contact. This transfer of kinetic energy continues throughout the material, allowing the heat to spread and warm the contents of the kettle.
What is the useful energy in a kettle?
The useful energy in a kettle is the thermal energy that heats up the water inside the kettle, allowing it to reach the desired temperature for preparing beverages or food. This energy is essential for the kettle to fulfill its purpose of boiling water efficiently.
What energy transfer takes place in a kettle?
In a kettle, electrical energy is transferred to thermal energy as the heating element inside the kettle generates heat. This heat then transfers to the water, increasing its temperature and causing it to boil.
