What else can I help you with?
When an atom undergoes radioactive decay the energy released in the reaction comes from what?
The energy released in radioactive decay comes from the conversion of mass from the parent atom into energy according to Einstein's famous equation, E=mc². This energy is released in the form of radiation or kinetic energy of the decay products.
Where does all energy ultimately come from on earth?
The Sun, unless it is geothermal energy (heat form the Earth's core) which originates from radioactive decay.
Does water released back into the environment ever come in contact with the radioactive fuel rods?
No, it doesn't.
Light and heat energy are being released from the fire where is the energy come from?
The energy in a fire comes from the chemical reactions taking place as fuel is burned. When the bonds between atoms in the fuel molecules break, they release energy in the form of heat and light. This process is known as combustion.
What happens to the particles of a substance as you take energy away?
As energy is taken away from a substance, the particles within the substance slow down and lose kinetic energy. Eventually, the particles may form a solid structure as they come closer together due to the reduction of thermal energy.
Where does the energy for heating magma come from?
It comes from inside Earth, which is always very hot. The internal heat is due to a combination of factors. The two most significant are residual heat from Earth's formation and energy released by radioactive decay of certain isotopes inside the planet.
Which example involves a phase change in which heat energy is released by the substance?
An example of a phase change where heat energy is released by the substance is the process of condensation. During condensation, a gas transforms into a liquid, and as the gas molecules lose energy and come closer together, they release heat into the surrounding environment. This is commonly observed when water vapor in the air condenses into liquid droplets, such as on a cold glass or during the formation of clouds.
Where did the store energy of earthquake come from?
I believe it's related to the heat from Earth's interior, which in turn is mainly due to radioactive decay.
What ore does radon come from?
Radon is released from any substance containing traces of uranium or radium. These substances, which include most rock and soil, are found worldwide. Radon gas is released by the emissiom of alpha particles from these radioactive substances.
When freezing happens is energy added?
No, in freezing, energy is actually removed from a substance. As the temperature drops, the molecules within the substance slow down and come closer together, eventually forming a solid state. This process releases energy in the form of heat.
What happens to the energy if an electron moves away from a proton?
to have a proton come out of a nucleus the atom must be a large radioactive element, meaning its so big its unstable and particles come off. the particles that are released is the radiation so the proton is called alpha radiation the energy is purely its high speed momentum. the energy of a proton coming of a nucleus is technically mechanical energy.
What happens when energy is taken away from matter?
The substance's particals will start slowing down and come closer together. As kinetic energy is removed from a substance, it will do the opposite as when kinetic energy is added to a substance.
