The sunlight millions of years ago allowed organic life and materials to develop and populate the earth. After the normal life cycles of generations of these plants and beings ended they returned to the earth and decayed, becoming what are now the gas and oil fields that produce the fossil fuels we have been using for nearly 200 years to power most everything in our daily lives.
What else can I help you with?
Why are stars sometimes referred to as atomic furnace?
Because by definition, that is what a star is - it is a huge ball of hydrogen, who's temperature and pressure near it's core is constantly converting hydrogen into helium by nuclear fusion. In two words, an "atomic furnace".
Energy exists in two states what are they?
Energy exists in many more than two states, but two are light energy and heat energy.
What does the sun's energy have to do with the weather?
The heat from the energy warms
What energy source don't come from the sun?
Tidal energy, geothermal energy, and nuclear energy are examples of energy sources that do not directly come from the sun. Tidal energy is generated by the gravitational forces of the moon and sun, geothermal energy comes from heat within the Earth's crust, and nuclear energy is produced by splitting atoms in a controlled reaction.
Does geothermal energy depend on the sun?
No, geothermal energy does not depend on the sun. It relies on heat stored beneath the Earth's surface from the decay of radioactive elements and residual heat from the planet's formation. This heat is harnessed to generate electricity or heat buildings.
How is mitochondria like the furnace in a house?
The Mitochondria produces energy for the cell and a furnace produces heat energy for your house.
What is the first step to replacing my electric furnace with a gas furnace?
Meet with your installer to determine the capacity of your new furnace. The furnace capacity should be matched with the size of the house. You want to get a furnace that heats a house without overheating the home. Because your furnace will be newer, it will take less energy to heat your home.
What would represent a mitochondria in a house?
The Battery. Since the mitochondria makes energy for the cell, a battery would be a suitable item.
What is a basement appliance that can heat your house?
A basement of a house is the room or space that is below ground level. A basement appliance that can heat your house is a furnace.
Does a furnace use radiation conduction or convection how do you know?
All three.A furnace burns something, this creates heat which can dissipate in those 3 ways.All 3 occur:Radiation: the fire radiates heat which can be seen with infrared goggles.Convection: The fire heats up air which rizes and leaves the system.Conduction: The fire heats up the materials of the furnace, causing the heat energy to heat up the air on the outside of the furnace, which in turn convect.
What are the radiations emitted by hot furnace?
A hot furnace emits primarily infrared radiation, which is a form of heat energy. This radiation is invisible to the human eye but can be felt as heat when in close proximity to the furnace.
Why does a central furnace kick on too much?
There is the possibility it is oversized causing it to heat the house, shut off and restart otherwise known as short cycling. Ideally the furnace would be sized to heat the house at the same rate the house loses heat on a design day.
Where does heat energy originate from?
Heat energy originates from the movement of atoms and molecules within an object. This movement creates kinetic energy, which is then transferred as heat energy.
Where does the heat from a furnace keeping your house warm go?
The heat pretty much stays in your house. The heat from the furnace rises (because the molecules have moved apart) and goes to the top of the house. There it cools down, and because it is not more dense, it sinks back down to the furnace where it can be made warm again. All this happens through a process of heat transfer call convection.
Does a house furnace support the first law of thereodynamics?
Any large group of particles will support the laws of thermodynamics, so yes.The 1st law is that energy can not be created or destroyed, it can only change form.In a house furnace the fuel reacts with oxygen in the process called combustion. This is an exothermic reaction which means it releases heat. The heat is energy so the question is where did the energy for the heat come from? Certain chemical bonds are stronger than others. If a strong bond is formed it will release more heat than a weaker bond forming. Breaking the bond requires the same amount of energy. Therefore combustion changes the energy in the chemical bonds to heat energy.
What type of energy does a furnace use?
A furnace can be heated by fossil fuels like coal, coke, or natural gas, which is chemical energy or it can be electric.
What is an analogy for mitochondria in a house?
Mitochondria in a cell can be compared to the furnace in a house. Just like mitochondria produce energy for the cell, furnaces produce heat for the house. Both are essential for the functioning of their respective systems.
