Why does a small spark have a much higher temperature than a hot kettle of water but less heat energy?

You must consider not only the temperature, but also the mass and the heat capacity. In this case, you can expect large differences mainly in the mass.

How can you transform electrical energy into thermal energy?
Yes, any time a current passes through a wire, part of the electricity will be converted into heat. This is used in a lightbulb (a small part of the heat then gets converted into light), in a shower, in an iron (for ironing your clothes), and others.AnswerThe term, 'thermal energy' is obsolete, having been replaced by the term, 'internal energy'. Yes, you can convert electrical energy into internal energy. That's what happens, for example, when you boil a kettle. The process of converting one form of energy into another is called 'work', so the kettle is doing work whenever it converts electrical energy into the water and increasing its internal energy. An increase in internal energy is accompanied by an increase in temperature. Whenever the temperature of the water exceeds the surrounding temperature, energy is lost to the surroundings through heat transfer. Heat is a process defined as energy in transit from a higher temperature to a lower temperature.
Why does it take longer for a full kettle of water to boil than a half full kettle?
The more water in the kettle, the longer it will take to reach boiling point. This is why it is wasteful in energy to boil a full kettle if you only want to brew a small cup of tea.
How does temperature affect the height that a dropped ball bounces?
When the ball is at a low temperature, the molecules are not flexible and bounce only to a small height. On the other hand, if the ball is warm or at a higher temperature, it will bounce longer heights.
Why does a wave with a large amplitude carry more energy than one with small amplitude?
It is the same as why an object at higher place had more energy than one on the floor. Energy is the difference of potential, for kinetic energy example it is the height, greater height is greater energy. For the wave, energy could be stored in amplitude and frequency. Low amplitude or no amplitude is no energy and any amplitude higher than the zero amplitude would have more energy.
How is electrical energy transformed into light energy in a toaster?
The main purpose of a toaster is to generate heat, not light. A small amount of light may be produced as a by-product, due to the high temperature. The way the heat (and a small amount of light) is produced is simply by using electrical resistors.

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.

Why does the fifty-two degree small cup full of water have a higher average of kinetic energy then a tub full of fifty-degree celsius water?
The 52o water molecules are moving faster than the 50o water molecules because temperature is a measure of the average kinetic energy of the molecules. The higher the temperature, the higher the kinetic energy, regardless of the amount of the substance.
What is the name of a small depression created by the melting of a chunk of ice in glacial sediment?
a kettle
Is this how you spell kettle?
Yes, that is the correct spelling of the word kettle.Some example sentences for you are:I will go and put the kettle on.We need to buy a new kettle.
Why does an egg casserole fall after it is taken out of the oven?
Casserole mass includes a lot of small bubbles. The bubbles contain gas. The gas pressure helps to keep shape of casserole. Gas pressure depends on temperature the higher temperature the higher pressure is. The temperature inside the oven is more higher then the temperature of kitchen.
How is temperature and heat different?
We have all noticed that when you heat something up, its temperature rises. Often we think that heat and temperature are the same thing. However, this is not the case. Heat and temperature are related to each other, but are different concepts. Heat is the total energy of molecular motion in a substance while temperature is a measure of the average energy of molecular motion in a substance. Heat energy depends on the speed of the particles, the number of particles (the size or mass), and the type of particles in an object. Temperature does not depend on the size or type of object. For example, the temperature of a small cup of water might be the same as the temperature of a large tub of water, but the tub of water has more heat because it has more water and thus more total thermal energy. It is heat that will increase or decrease the temperature. If we add heat, the temperature will become higher. If we remove heat the temperature will become lower. Higher temperatures mean that the molecules are moving, vibrating and rotating with more energy. If we take two objects which have the same temperature and bring them into contact, there will be no overall transfer of energy between them because the average energies of the particles in each object are the same. But if the temperature of one object is higher than that of the other object, there will be a transfer of energy from the hotter to the colder object until both objects reach the same temperature. Temperature is not energy, but a measure of it. Heat is energy in short heat is the cause and temperature it's effect.........
What is a small depression formed when a block of ice melts in tills?
kettle
If the kitchen countertop has a small toaster and an electric kettle, you should?
Yes
How are potential energy and stability related?
the higher the potential energy, the more is the stability....
When cells has more energy available how can it store small amounts of that energy?
Cells break down the higher-energy molecules and store the energy that is released in molecules of ATP. This is called cellular respiration.
