Hydrocarbons are part of fuels such as petrol, diesel and gaseous fuels such as paraffin gas.
They are released in the atmosphere whenever they are 'released' without being burnt! For example, petrol drips on to the forecourt at every refill and evaporates into the atmosphere.
An example from within an engine is when the spark plug ignites the fuel-air mixture, a tiny fraction of the mixture remains unburned and is released in the exhaust emissions.
What else can I help you with?
Where does this energy come from once the hydrocarbons release a lot of energy when ignited?
This is the heat of combustion.
Where is energy stored in an unlit candle?
the energy stored in an unlit candle is chemical potential energy, and it is stored in the bonds between the atoms in the hydrocarbons (wax) that make up the candle.
Why do hydrocarbons contain so much energy?
Hydrocarbons contain a high amount of potential energy in their chemical bonds because they are made up of carbon and hydrogen atoms, which have strong bonds that store a lot of potential energy. When these bonds are broken through burning or other reactions, the stored energy is released in the form of heat and light. This makes hydrocarbons a valuable source of energy for human activities.
What property of hydrocarbons that make them useful as fuel?
the advantages are that it gives of heat and energy. the disadvantages are that it is not easily stored
Why are hydrocarbons used for fuel in stoves cars and airplains?
Like many other organic compunds, hydrocarbons mix poorly with water. Also, all hydrocarbons are flammable. Being flammable means that they burn easily. When hydrocarbons burn, they realease a great deal of energy. For this reason, they are used as fuel for stoves, heaters, cars, buses, and airplanes.
An example of stored chemical energy?
Gasoline is an example of stored chemical energy. The hydrocarbons in gasoline store energy in their chemical bonds, which is released when the fuel is burned to power engines.
Where does this energy come from once the hydrocarbons release a lot of energy when ignited?
This is the heat of combustion.
Where is energy stored in an unlit candle?
the energy stored in an unlit candle is chemical potential energy, and it is stored in the bonds between the atoms in the hydrocarbons (wax) that make up the candle.
What type of energy is energy stored in gasoline?
Gasoline is a mixture of hydrocarbons. As gas is burned, the compounds are broken down into simplier compounds and the breaking of these compounds releases energy.
Why do hydrocarbons contain so much energy?
Hydrocarbons contain a high amount of potential energy in their chemical bonds because they are made up of carbon and hydrogen atoms, which have strong bonds that store a lot of potential energy. When these bonds are broken through burning or other reactions, the stored energy is released in the form of heat and light. This makes hydrocarbons a valuable source of energy for human activities.
Does oil is chemical energy?
Yes, oil is a form of chemical energy. It is made up of hydrocarbons which contain stored energy that can be released through combustion to produce heat and other forms of energy.
Where does the energy that is stored in food come from?
sunlight
Where does the energy that is stored from food come from?
sunlight
Where does the energy for a rocket's liftoff come from?
Chemical energy, stored in the fuel.
Where does the energy come from to light a match?
Chemical energy, stored in the match.
How does the burning of hydrocarbons release energy?
When hydrocarbons are burned, the chemical bonds in the molecules are broken, releasing energy in the form of heat and light. This process involves combining the hydrocarbons with oxygen to form carbon dioxide, water, and other byproducts, which leads to the release of energy that was stored in the bonds of the hydrocarbons.
What type of energy iss stored in fuel?
The energy stored in fuel is primarily chemical energy. This energy is contained within the bonds of the molecules that make up the fuel, such as hydrocarbons in fossil fuels or carbohydrates in biofuels. When fuel undergoes combustion or other chemical reactions, this stored chemical energy is released, usually in the form of heat and light, which can then be converted into mechanical or electrical energy.
