Can matter be converted to energy?
– Matter can be converted into energy by the process of nuclear fission. – Nuclear fission is a reaction in which the particles or atoms split into two smaller and lighter nuclei. With this fission, it will release a huge amount of energy.
How do matter and energy change during a chemical reaction?
All chemical reactions involve energy. Energy is used to break bonds in reactants, and energy is released when new bonds form in products. Endothermic reactions absorb energy, and exothermic reactions release energy. The law of conservation of energy states that matter cannot be created or destroyed.
What happens to matter in a chemical reaction?
In reactions under normal laboratory conditions, matter is neither created nor destroyed, and elements are not transformed into other elements. Because matter is not created or destroyed in a chemical reaction, the total mass of reactants is the same as the total mass of products.
What is E mc2 used for?
E = mc2, equation in German-born physicist Albert Einstein’s theory of special relativity that expresses the fact that mass and energy are the same physical entity and can be changed into each other.
How is matter created or destroyed during a chemical reaction?
Answer 1: A chemical reaction does not create or destroy matter, it simply moves electrons from one atom to another, but does not change the nucleus of the atoms. The total mass of the matter remains a constant in any chemical change. The total mass of the matter can change during a nuclear reaction, the mass loss can convert into energy,…
What happens to matter when it is converted into energy?
Instead of talking about “matter” turning to “energy”, it is more proper to talk about mass as a form of energy, so there is no question of “conversion”: mass is already an energy.
When is energy converted to mass in a particle?
The conversion of energy, kinetic or electromagnetic, to particles with rest mass is experimentally observed only when the energy comes in big enough clumps to create a massive particle, when the energy is low, this is going to be the lightest charged particle, the electron.
Can a change in mass in a chemical reaction be measured?
This change in mass in chemical reactions, however, is so small that it’s difficult to measure. Really only nuclear reactions can be measured in terms of the reactants weighing more than the products (which is why nuclear reactions are so powerful). Matter cannot be created or destroyed in a chemical reaction; it is rearranged.
