How did early scientists think that the sun produces its energy?
The burning of fuel.
What fuel is the sun using to release energy?
Our sun, Sol, uses hydrogen for fuel.
Does the sun's energy come from the burning combustion of hydrogen?
No. The sun's energy comes from the nuclear fusion of hydrogen, not combustion. In this reaction hydrogen atoms fuse with one another to form helium atoms. The fusion of hydrogen yields about 4.5 million times more energy than you would get from burning the same amount.
Why can you say that energy from fossil fuel burning energy comes from the sun?
Because the energy comes from free carbon and oxygen that produce heat when they are recombined to form CO2 (carbon dioxide). The fossil fuel contains hydrocarbons that can be burned to produce CO2, water and heat. The fossil fuel material was formed millions of years ago by photosynthesis, when plants took in CO2 and separated the carbon from the oxygen, using the Sun's rays. The carbon was used in the production of tissues for the planets, and the oxygen was released into the atmosphere. So the energy that comes from burning fossil fuels came originally from the Sun by photosynthesis.
What are some disadvantages about using solar energy?
Initial costneed to store energy for times of no Sun
When you burn coal oil and gas for energy how are you using stored energy from the Sun?
yes
What is energy from burning organic materail?
Chemical energy (originally from the Sun).
What are limitations of using energy from the sun?
well when you use energy form the sun it takes away from the money that oil compan ies make off of you which could be bad for the economy
What are the advantages of using solar energy instead of coal and oil for energy?
The main advantage of using solar energy is that it is renewable. The sun produces more energy in a minute than the planet uses in a year, and will take several billion years to run out. The sun also does not pollute. Coal and oil, however, will run out, and the emissions produced by them are very harmful.
What living thing can make food using the sun's energy?
Plants can make food using the sun's energy.
How did early scientists think that the sun produces its energy?
The burning of fuel.
Do corn oil and petrol get their energy from the Sun Both corn oil and petrol are sources of energy Petrol comes from crude oil which is formed from the remains of dead organisms Explain?
By the food chain all animals get their energy from eating other animals which eat plants, plants make energy using sunlight therefore the dead animals all got their energy from sunlight, the dead animals became crude oil therefore, crude oil gets its energy from the sun QED
What is the original source of energy for oil?
The sun
Why can you say that the energy obtained by burning fossil fuels originated by the sun?
your not cool.
Where did plants get their energy from?
Solar energy from the sun using photosynthesis.
What type of energy produces oil?
The energy stored in mineral oil is in the form of carbon that produces energy when it forms atomic bonds with oxygen to form carbon dioxide in the burning process. That energy was originally stored when plants used to Sun's energy to separate carbon and oxygen from atmospheric carbon dioxide millions of years ago, by photosynthesis. Plants used the carbon to form tissues made from long chains of carbon atoms. In that way, burning oil, coal and natural gas releases the Sun's energy, stored millions of years ago. 1 kg of fossil fuel burns with approximately 2.5 kg of oxygen to produce 3.5 kg of carbon dioxide.
How does the sun recreates back the burning gases?
The Sun does not recreate the gases it fuses to make energy. Eventually, in about 4 billion years, the Sun will run out of energy and become a red giant.
