Is a boiling kettle useful or wasted energy?
A boiling kettle is useful for preparing hot water for drinks or cooking. However, leaving a kettle boiling for an extended period would waste energy unnecessarily. It is best to boil only as much water as needed to be energy-efficient.
What is the useful and wasted energy in an electric heater a television an electric kettle headphones Thanks for your help?
In an electric heater, the useful energy is the heat generated for warming the room, while the wasted energy is the heat lost through the surroundings. In a television, the useful energy is the light and sound produced for viewing and listening, while wasted energy can come in the form of heat generated by the device. In an electric kettle, the useful energy is the heat used to boil water, while wasted energy can be heat lost through the kettle's exterior. In headphones, the useful energy is the sound produced for listening, while any energy lost through heat or vibration could be considered wasted.
What type of energy does a kettle use and what types of energy does it get converted to?
A kettle uses electrical energy and converts it into heat energy.
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 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.

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.
What type of energy does a kettle use and what types of energy does it get converted to?
A kettle uses electrical energy and converts it into heat energy.
How does an electric kettle get energy?
The kettle has to be plugged in to an energy supply before it can heat up.
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 wasted energy for a kettle?
By the fact that the kettle is hot. The heat energy is also warming the metal of the kettle. By the fact that the water boils to steam,; loss of water to steam. The energy should only heat the water to boiling point, and not heat the kettle nor allow the water to boil off.
What is the energy input for a kettle?
The energy input for a kettle is typically provided by electricity or gas. The energy is used to heat the water inside the kettle to the desired temperature for various purposes such as making hot beverages or cooking.
What energy transformations are in a kettle?
Electrical energy to kinetic energy
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 energy does a kettle use to heat water?
A kettle typically uses electrical energy to heat water. When turned on, the electric current passes through a heating element in the kettle, which converts the electrical energy into heat energy that warms the water.
