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 else can I help you with?
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.
Is steel kettle metallic or non mettalic?
Steel kettle is metallic.
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 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 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 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 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 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
How do you determine mechanical thermal and relative efficiency?
Mechanical efficiency is determined by dividing the output work by the input work, while thermal efficiency is calculated by dividing the useful work output by the heat input. Relative efficiency is the ratio of mechanical efficiency to thermal efficiency and can be used to compare the effectiveness of a machine in converting input energy to useful work.
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.
What is thermal efficiency of petrol engine?
The maximum Thermal Efficiency of Petrol Engine or Gasoline Engine or Otto Cycle Engine is about 25-30%.
What is thermal efficiency?
Thermal efficiency is a measure of how efficiently a system converts heat energy into mechanical work. It is calculated by dividing the desired output (such as work) by the input energy (such as heat) and is expressed as a percentage. Higher thermal efficiency indicates that more of the input energy is being converted into useful work.
