How can a cup of very hot tea have less thermal energy than a kettle of lukewarm water?

Even though the cup has very hot water it still has less thermal energy than the kettle because the kettle is larger than the cup therefor it has more liquid and more liquid = more molecules and the more molecules the more the heat energy ( thermal energy ) It does not matter how fast the particals are moving just how many there are , the cup has a lot less particals than the kettle so it has less thermal energy. This was wrote by an 11 year old just think about that .

∙ 12y agoyou are asking 'hot' teacup vs 'warm' kettle.
If the universe were 'warm', it would have more thermal energy than a hot' teacup, regardless of the temperature - thermal energy - of the teacup, or it would not exist from 'burning' up.
the kettle and the teacup sizes must be defined before the thermal energy can be determined, as well as the specific temperatures involved.

What happens to thermal energy when you mix hot and cool water together?
Since hot water is less dense that cold air the hot water will rise and the cold would sink then it keeps doing this in a circular motion 'till the thermal energy reaches to thermal equilibrium.
Example of chemical to thermal energy?
You could burn a fire.
What are the advantages of an eco kettle?
Until now, conveniently measuring the correct amount of water to be boiled in your kettle has not been easy. It is estimated that, on average, we boil twice the volume of water needed every time. Which means twice as much energy, twice as much time. An eco kettle allows you to boil just the right amount of water every time.
2 glasses of water have the same thermal energy must they have the same temperature explain?
How you can tell is the temperature between the two liquids. If one of the liquid's temperature is warmer than the other one, then that liquid has more thermal energy.
If a bathtub and a cup contain water at the same temperature which will have more thermal energy?
-- Temperature is the direct observation of the average kinetic energy of themolecules in the substance.-- If the tub of water and cup of water have the same temperature, then theaverage kinetic energy of the molecules in each one must be the same.-- The tub full of molecules needs more total energy than the cup of molecules does,in order to average the same for each molecule.
What kind of energy is water boiling in a kettle?
To clarify, water - or any other subject IS not energy; rather, it HAS energy. In this case, the relevant energy is the thermal 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 energies come out of a kettle?
When a kettle is in use, the primary forms of energy involved are electrical energy and thermal energy. Here's how these energies are involved in the process: Electrical Energy: The kettle is connected to an electrical power source, and electrical energy is supplied to the heating element inside the kettle. The heating element is usually made of a resistive material, such as nichrome, which resists the flow of electricity, leading to the generation of heat. Thermal Energy: The electrical energy is transformed into thermal energy as the resistive heating element heats up. This thermal energy is transferred to the water inside the kettle, raising its temperature and causing it to boil. Heat Energy: The thermal energy generated in the heating element is transferred to the water, converting it from a liquid state to a gaseous state (steam) during the boiling process. Kinetic Energy: As steam is generated, it expands and exerts pressure, leading to the movement of steam molecules. This movement represents kinetic energy. Sound Energy: The boiling water and the release of steam can also produce sound energy. The bubbling and hissing sounds are examples of sound energy associated with the operation of a kettle. While electrical and thermal energies are the primary forms involved, the process of boiling water in a kettle can manifest in various forms of energy depending on the specific conditions and the environment
What is an example of converting electrical energy into thermal energy?
Water heater, kettle, soldering iron, iron box, induction stove, microwave oven
What is the energy input for a kettle?
Electrical energy transformed into Thermal energy (heat) and Mechanical energy (sound)
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.
How does energy change when you turn the kettle on?
The evaporation of water by boiling is the transfer of thermal energy (radiation or convection) to the molecules which form water vapor. The energy is the same, but it changes from kinetic to potential energy. As the water vapor gives up heat by conduction in the air, the water again condenses (dew, rain, ice, snow).
What are the benefits of drinking lukewarm water?
The benefits of drinking lukewarm water is that your body doesn't have to cool the water from hot water or warm up the water from cold water. This saves energy and does not put stress on your body.
What is oceanic thermal energy?
Oceanic thermal energy is the heat energy that is stored by the water in the ocean.
Examples of thermal energy?
When you rub your hand together really fast. Do your hand feel warmer after rubbing them together? That's because the particles in your hand run into each other run into each other and pass energy back and forth, which increases heat. When particle in an object run into each other, thermal energy is passed between the particle.Another AnswerThe term, 'thermal energy' is obsolete, having been replaced by the term, 'internal energy'. Internal energy is the sum total of all the energies due to the vibration of the atoms/molecules that make up any object. Internal energy is closely related to temperature and state. The higher the temperature of an object, the higher its internal energy. When a substance exists in two states at the same temperature, e.g. ice and water, the higher state (water, in this example) will have the higher internal energy.When an electric current passes through the heating element of a kettle, it does work on the water and the kettle. By 'work', we mean the process of converting one form of energy (e.g. electrical energy) into another form of energy (e.g. internal energy). When the electrical energy is converted into internal energy, the existing internal energy of the water/kettle increases, causing the temperature of the water/kettle to increase. The resulting temperature difference between the kettle and the surrounding air results in a loss of internal energy by the process of heat transfer away from the kettle.
When water in a kettle is boil it transform energy into what?
Boiling Water OBV!
Where you buy lukewarm water?
You don't buy lukewarm water, you heat water until its lukewarm.
