Energy

The Energy category covers the description, definition, and use of all types of energy. Questions of a general nature can be put in the general Energy category. Other sub-categories exist for Fossil fuels, Nuclear energy, and renewables such as Wind, Solar, Hydro, Tidal, and Wave power.

What is matter and energy second law of thermodynamics?

The second law of thermodynamics states essentially that it is impossible for heat to flow from a cooler body to a hotter one, without the performance of work by an external agency. I'm not sure how this relates to your wording of 'matter and energy'.

What form of energy does a fridge have?

A fridge uses electrical energy to power its compressor, fan, and other components that help keep the interior cool. This electrical energy is converted into heat energy as the fridge removes heat from the inside and releases it outside.

What energy transformation in playing a game sipa?

In playing the game sipa, the energy transformation involves converting potential energy from the player's leg muscles into kinetic energy as they kick the sipa. As the player's foot makes contact with the sipa, some of the kinetic energy is transferred to the sipa, causing it to move. Frictional forces between the player's foot and the sipa also result in some energy being converted into thermal energy.

What are non-examples of the law of conservation of energy?

When water is used to produce electricity.In this process, firstly,water is allowed to fall from great heights,so potential energy is converted to kinetic energy(K.E.). Then this energy is used to rotate the turbine of a generator which produces electricity. Thus potential energy of water in a dam is converted into kinetic energy which is then converted to electric energy.

What term is defined as a measure of the energy of the energy of motion of particles in a substance?

The term defined as a measure of the energy of motion of particles in a substance is temperature. Temperature is related to the average kinetic energy of particles in a substance, where higher temperatures correspond to greater kinetic energy and vice versa.

What are 3 forms of energy that light can be transformed or converted into when it has been absorbed by a surface?

Light energy can be transformed into thermal energy (heat), chemical energy (in photosynthesis), and electrical energy (in photovoltaic cells) when absorbed by a surface.

What is the amount of energy stored in a molecule?

The amount of energy stored in a molecule depends on its chemical bonds and structure. This energy is typically measured in units like kilojoules per mole or electron volts. The energy stored in a molecule is released or absorbed during chemical reactions.

Name a few functions in your body that require energy?

walking, carrying objects, thinking, blood circulation, digestion, sports, ... etc

How is fission used to calculate the energy required?

In nuclear fission, the energy released is calculated using the mass defect principle expressed by Einstein's equation E=mc^2, where E is energy, m is mass defect, and c is the speed of light. The mass defect is the difference in mass between the reactants and products of the fission reaction, and this mass defect is converted to energy according to Einstein's equation.

Which would provide the body with the energy?

Incorrect, it's actually "Breaking bonds in a Polysaccharide" Tested.

(Apex.)

What is one difference between biomass energy and energy and wind energy?

== == Biomass shows us the total dry weight of the organisms in the trophic level.. example: 100,000 kg of plants (and by this we don't mean that one plant weighs 100,000 kg we mean that the total no. of plants that are eaten by grasshoppers weigh 100,000 kg )are eaten by 10,000 grasshoppers which are eaten by 100 kg birds which area eaten by a 3 kg snake.. Now on the other hand.. an energy pyramid shows us the energy flow in an enviroment, producers will always have the most energy followed by first degree consumers ( herbivores ) and then secondary consumers ( carnivores ).... Hope i Helped those in need :P...... nice topic thnx for bringing the question up Peace out :D..

Water draining from a tower is an example of what kind of energy conversion?

Gravitational potential energy being converted to kinetic energy

What happens to the molecules in a substance when thermal energy is removed?

When thermal energy is removed from a substance, the molecules lose kinetic energy and slow down. This often causes the substance to cool down as the molecules have less energy to move and vibrate. In extreme cases, the substance may undergo a phase change, such as from a liquid to a solid.

How is the sun related to electromagnetic nuclear and heat energy?

The Sun emits electromagnetic and heat energy; we receive that.The Sun gets its energy from nuclear energy; specifically, converting hydrogen-1 into helium-4.

What are the Two types of injury for electrical energy passing through the body?

The two main types of injury from electrical energy passing through the body are electrical burns and cardiac arrhythmias. Electrical burns occur at the point of contact with the electrical source, while cardiac arrhythmias can result from the disruption of the heart's normal electrical activity. Both types of injuries can be life-threatening and require immediate medical attention.

What organelle in Animals help release energy?

The mitochondria is the organelle in animals responsible for releasing energy through the process of cellular respiration. This organelle produces adenosine triphosphate (ATP), the energy currency of the cell, through a series of biochemical reactions involving glucose and oxygen.

What is the temperature called at which no more energy can be removed form matter?

The temperature at which no more energy can be removed from matter is called absolute zero. This temperature is equal to 0 Kelvin (-273.15 degrees Celsius) and represents the lowest possible temperature that matter can reach.

Can electrical energy be produced from mechanical energy?

Yes, electrical energy can be produced from mechanical energy by using devices such as generators. When mechanical energy is applied to a generator, it induces a magnetic field that generates electricity through electromagnetic induction. This process is commonly used in power plants, wind turbines, and hydroelectric dams to generate electrical power.

What drives energy flow in chemical cycling on earth?

Energy flow in chemical cycling on Earth is driven by sunlight. Solar energy is captured by plants during photosynthesis and is then transferred through the food chain to other organisms. Microorganisms also play a key role in breaking down organic matter and releasing energy through processes like decomposition.

What kind of energy is energy motion?

The type of energy associated with motion is kinetic energy. Kinetic energy is the energy an object possesses due to its motion and is dependent on the object's mass and velocity. The faster an object is moving, or the more mass it has, the greater its kinetic energy.

What is energy stored within any physical thing called what?

Potential Energy.

What Potential Energy is, is a whole different question

What two forms of energy does a lightbulb produce?

A lightbulb primarily produces light energy through the emission of photons when electricity passes through the filament. It also produces a small amount of heat energy due to resistance in the filament that causes it to get hot.

What energy change takes place in a electric fire?

In an electric fire, electrical energy is converted into heat energy. The electricity passes through a resistor which generates heat through resistance, thus producing warmth and light in the process.
