When you burn wood in a campfire what energy is change?
Burning wood is an example of chemical energy changing into heat and light energy. Energy is not destroyed, it simply changes from one form to another.
Why do people burn coal and oil?
Heat can cause some matter to burn. Burning is a chemical change. When fuel burns, the energy stored inside it is released.
What is the energy flow diagram of a burning candle?
The wax in the candle contains chemical energy. When you burn the candle the chemical energy is transferred into heat (thermal) and light energy. :)
Where can brimstone commonly be found?
Brimstone (burn stone) is also known as "Sulphur" and occurs naturally as a pure element - sulphide. It can commonly found as a by product of removing unwanted sulphur contaminants from natural gas and petroleum.
Why did Dmitri believed petroleum was too valuable to burn?
I don't know who Dmitri is, but the idea is that petroleum can be used for many other things, apart from using it as fuel in cars, etc. For example, lots of synthetic substances (different kind of "plastics") are basically made from petroleum.
A chemical change occurs when a piece of wood is?
When you burn wood a chemical change occurs.
Can you put petroleum jelly on a burn?
Petroleum jelly has many uses. Petroleum jelly may be put on a burn to help soothe it. Petroleum jelly may also reduce scarring.
What energy transformation occurs when gasoline is burn?
The mechanical energy from the engine (with help from electrical energy from the battery), turns the potiential energy of gasoline/petrol into kinetic energy.
How do electrical power plants get energy?
Different types of plants get their energy from different sources. For example, some burn coal or petroleum, while others split radioactive isotopes to get nuclear energy.
Explain what kind of heat transfer occurs when you burn yourself on a hot car seat in the summer?
The burn comes from conductive heat energy.
What kind of energy does fuel contain?
Fossil fuels contain chemical potential energy, which is released as thermal energy when they burn. Nuclear fuel which can undergo fission contains energy by virtue of the change of mass which occurs when the nucleus is split into fragments, initially this is released as kinetic energy which is absorbed in the fuel and released as thermal energy.
Rockets need to have what in order to burn fuel?
They need petroleum in order to burn the fuel.
How is the heart rate of a person running different from their resting heart rate why is this change necessary?
Because your heart needs to burn energy, the more energy you burn the faster your heart rate
Why doesn't a cell burn up as it releases energy from organic molecules?
A cell does not burn up as it releases energy from organic molecules because the temperature at which metabolism occurs is the normal body temperature. This is an important component of the temperature-control mechanism of organisms.
How chemical change is useful to people?
Chemical change is useful because when it occurs, some desirable outcomes such as combustion occurs. Some reactions give off heat energy. Heat packs work by allowing certain chemicals to mix and give off heat.
What did Alexander great burn to scare away his enemies elephants?
petroleum
What does Cellular respiration need?
Oxygen and a source of Fuel/Energy, and a Cell. "Lactic Acid Burn", that occurs to overworked muscles, occurs during Respiration that takes place without enough oxygen at the time.
