Does the suns energy come from burning fuels like oils?
No, the sun's energy is a byproduct of nuclear fusion, primarily hydrogen gas "burned" into helium. There are no significant quantities of complex organic hydrocarbons in our sun. While there is oxygen, the hydrogen/oxygen or carbon/oxygen chemical reaction is not what results in solar energy.
How does a star burn without oxygen?
The "burning" that takes place in a star is not fire. It is nuclear fusion. In the process hydrogen atoms fuse with one another to form helium, releasing millions of times more energy than can come from any fire.
Where does the source of the sun energy come from?
The Sun gets its energy from nuclear fusion. Specifically, converting hydrogen-1 into helium-4.
Does the sun's energy come from electromagnetic energy?
Yes, the sun's energy is primarily generated through nuclear fusion reactions in its core, not electromagnetic energy. These fusion reactions convert hydrogen into helium, releasing vast amounts of energy in the form of electromagnetic radiation, including visible light, ultraviolet light, and infrared radiation.
What is solar energy and where does it come from?
Solar energy is energy from the Sun that is converted into thermal or electrical energy. It comes from the Sun's nuclear fusion reactions, where hydrogen atoms combine to form helium, releasing vast amounts of energy in the form of sunlight. This energy can be harnessed using solar panels to generate electricity or heat.
What are the 4 steps in hydrogen combustion?
Hydrogen combustion involves four key steps: Initiation: Hydrogen and oxygen molecules come into contact, often requiring an initial energy source (like a spark) to overcome the activation energy barrier. Propagation: The reaction rapidly proceeds as hydrogen molecules react with oxygen, forming water vapor and releasing energy in the form of heat and light. Termination: The reaction continues until the available hydrogen or oxygen is consumed, or until the temperature drops below the necessary threshold to sustain combustion. Product Formation: The primary products of hydrogen combustion are water (H₂O) and heat, contributing to a clean energy release with minimal pollutants.
Does fire need energy?
Yes, fire does require energy to ignite and continue burning. This energy can come from sources such as heat, light, or a chemical reaction. Once the fire is burning, it releases energy in the form of heat and light through a process called combustion.
Do hydrogen cars make polution?
A car fueled with hydrogen is not a pollution source, since the combustion product of hydrogen is water vapor (which is, technically, a greenhouse gas, but the hydrogen was almost certainly produced by elecrolysis of water in the first place, so it cancels out). The carbon footprint of actually producing the car and maintaining it, however, may be significant. Particularly since the energy for electrolysis to produce the hydrogen to run it has to come from somewhere, and most of our electricity comes from burning fossil fuels.
Were does the light and heat from burning wood come from?
The light and heat from burning wood come from the chemical reaction called combustion. When wood burns, the heat and light are produced as a result of the energy released from the chemical bonds breaking down and forming new compounds. The heat provides the energy necessary for the reaction to continue, while the light is a byproduct of the reaction.
Where does this energy come from once the hydrocarbons release a lot of energy when ignited?
This is the heat of combustion.
What 3 energy transfers come a burning candle?
Three main things come from a burning candle: light, heat, Thermal energy x
Does the suns energy come from burning fuels like oils?
No, the sun's energy is a byproduct of nuclear fusion, primarily hydrogen gas "burned" into helium. There are no significant quantities of complex organic hydrocarbons in our sun. While there is oxygen, the hydrogen/oxygen or carbon/oxygen chemical reaction is not what results in solar energy.
Where does CO2 and H2O come from in a flame?
The resulting compounds of any burning (oxidation) reaction of organic materials are water and carbon dioxide.
Does energy come from burning fossil fuels?
Yes, certainly it does
A device that converts thermal energy into mechanical energy is a?
This is a heat engine, they come in various types such as internal combustion, external combustion, steam turbines, gas turbines, etc.
Where does the energy come from ATP at the chloroplast?
From the motion of hydrogen ions from the kinetic energy of hydrogen ions passing through ATP synthase
Where does the energy come from to make at at the chloroplast?
From the motion of hydrogen ions from the kinetic energy of hydrogen ions passing through ATP synthase
