Can you make matter out of energy?
Photon pair production. Thus, matter can be created out of two photons. The law of conservation of energy sets a minimum photon energy required for the creation of a pair of fermions: this threshold energy must be greater than the total rest energy of the fermions created.
If you can, however, transfer enough energy to the field, you can create a real particle-antiparticle pair. Thus yes, if you have energy, you can create matter, but only together with equal amount of antimatter.
- In keeping with the Law of Conservation of Matter, the mass of the products formed is equal to the mass of the reactants. Matter is neither created nor destroyed during the chemical reaction of photosynthesis.
- Heat is probably the easiest energy you can use to change your physical state. The atoms in a liquid have more energy than the atoms in a solid. There is a special temperature for every substance called the melting point. When a solid reaches the temperature of its melting point, it can become a liquid.
- During a molecular, atomic or nuclear transition to a lower energy level, photons of various energy will be emitted, ranging from radio waves to gamma rays. Photons can also be emitted when a particle and its corresponding antiparticle are annihilated (for example, electron–positron annihilation).
Essentially, the equation says that mass and energy are intimately related. Atom bombs and nuclear reactors are practical examples of the formula working in one direction, turning matter into energy.
- Types of Energy. There's kinetic (or movement) energy, gravitational potential (or stored) energy, elastic potential energy, chemical energy, light energy, sound energy, nuclear energy, mechanical energy, heat energy and many more.
- In fact it is not just nuclear fusion and fission that can transform matter (or mass) into energy. Any time energy is produced, some small amount of matter or mass is converted into energy.
- The Equivalence of Mass and Energy. According to Einstein's famous equation E = mc2, the energy E of a physical system is numerically equal to the product of its mass m and the speed of light c squared.
