Does an electron-positron collision violate the law of conservation of matter?

No, electron-positron collision does not violate the law of the conservation of matter. Momentum and charge are also conserved. Electrons and positrons can collide in what are called scattering events, and they can do this without necessarily undergoing mutual annihilation. Because both these little critters can exist as a wave (particle-wave duality), their behavior can be fairly easily assessed using a "basic tool kit" to analyze electromagnetic wave interaction. But electrons and positrons can annihilate each other rather than scatter. Annihilation doesn't violate the law of conservation of matter, either. And there's a reason for that. The "old" idea of the conservation of matter was that matter could neither be created nor destroyed. But we now know that matter can be converted into energy. That's what happens in annihilation. The article in Wikipedia on the annihilation event touches on electron-positron collision. And there is an article on electromagnetic scattering as well. They aren't that difficult to understand, and the curious person will find links to those posts below.

No, an electron-positron collision does not violate the law of conservation of matter. Energy is conserved in the process, with the production of other particles such as photons. While individual particles are not conserved, the total energy and momentum in the system remain constant.

What are some alike things to the law of conservation of matter?
The law of conservation of energy states that energy cannot be created or destroyed, only transferred or converted. The law of conservation of momentum states that in a closed system, the total momentum remains constant before and after a collision. The law of conservation of charge states that the total electric charge in an isolated system remains constant over time.
When is the conservation of matter true in a open system or closed system?
The conservation of matter applies in closed systems, where no matter can enter or leave. In open systems, matter can be exchanged with the surroundings, so the conservation of matter may not be strictly true.
What is another name for the law of conservation of matter?
The law of conservation of matter is also known as the law of conservation of mass. It states that mass is neither created nor destroyed in a chemical reaction, only rearranged.
What does the conservaton suggest about the conservation of energy the conservation of matter and the conservation of momentum?
Conservation laws suggest that energy, matter, and momentum cannot be created or destroyed but can only change forms or be transferred between objects. Conservation of energy states that the total energy in a closed system remains constant. Conservation of matter indicates that the total mass in a closed system is constant. Conservation of momentum asserts that the total momentum of an isolated system remains constant in the absence of external forces.
What is the law of conservation of matter and energy mean?
The law of conservation of matter and energy states that matter and energy cannot be created or destroyed, only transformed from one form to another. This principle is a fundamental concept in physics and chemistry, emphasizing the importance of balance and conservation in physical processes.
Can momentum be preserved in elastic and inelastic collision?
Momentum is always conserved in both elastic and inelastic collisions. In elastic collisions, kinetic energy is also conserved, whereas in inelastic collisions, some kinetic energy is converted into other forms such as thermal energy or sound.

The law of conservation of what?
If by the law of conservation you mean the Law of Conservation of Matter, then it states that matter cant be created or destroyed.
What is the laws of conservation?
If by the law of conservation you mean the Law of Conservation of Matter, then it states that matter cant be created or destroyed.
When rocks change form in the rock cycle we see an example of the conservation of what?

Does hydrogen peroxide obey the law of conservation of matter?
The law of conservation of matter is applied to processes not to a compound.

Conservation of energy states that the total energy in a closed system remains constant. Conservation of matter indicates that the total mass in a closed system is constant. Conservation of momentum asserts that the total momentum of an isolated system remains constant in the absence of external forces.
Two scientists claim they can use a chemical reaction to make matter how are they wrong?
They are wrong because the law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. The reactants and products in a chemical reaction must have the same total mass.
How can law of conservation of matter be used in a sentence?
The law of conservation of matter states that in a chemical reaction, matter is neither created nor destroyed.
Four physical quantities which have same dimensional formulae?
Conservation of Matter, Conservation of Energy, Conservation of Charge and Conservation of Momentum.
What law states that mass cannot be created or destroyed in chemical or physical changes?
The law of conservation of mass/matter states that mass/matter cannot be created or destroyed in chemical or physical changes.
