What is conserved in physical changes?
Mass and energy
Does Einstein's famous equation suggests that mass and energy together are conserved or not?
Einstein wrote more than one 'famous equation', but the one you mean is e=mc2 . This shows that mass may be converted to energy, or energy to mass, under the right conditions. c2 gives the rate of exchange between the two. Since c (the speed of light) is a large number, its square implies a ruinous exchange rate if you want to create mass, and a good deal if you can turn mass into energy. In any closed system you can begin by measuring the quantities of energy and mass, then use the equation to convert mass to energy, or vice versa. Then, whatever you do in your closed system, the total mass equivalent, or energy equivalent, will remain what it was before. In short, mass-energy is conserved.
In what way does the big bang theory conform with the law of conservation of matter?
It doesn't. In General Relativity, energy (and therefore mass) is NOT conserved - and the Universe on a large scale is described, to a great extent, by General Relativity. The reason energy is not conserved is simply that the conditions for Nöther's Theorem are not fulfilled, due to the expansion of the Universe.Note that under ordinary, everyday circumstances, the conditions for Nöther's Theorem ARE fulfilled, and energy (and therefore mass) IS conserved.
Why can the law's name be Conservation of Matter or Conservation of Mass and still be the same?
In both cases, something is conserved - it doesn't change over time.Also, mass and energy are equivalent. If something has energy, it has mass, and vice versa.
How is energy conserved with nuclear fission?
Energy is always conserved. You can neither create nor destroy energy. The same goes for mass. They can only be moved from one frame of reference to another. Fission has nothing to do with it. Ditto for fusion.One area of "confusion" for many people is Einstein's mass-energy equivalence equation e = mc2. Some people think it means that mass can be converted to energy and vice versa. Nope. Not even close. Mass is energy, and energy is mass. Think about that.
What is the exception for conservation of energy?
The exception to the conservation of energy is in systems where energy is converted into mass or mass into energy, according to Einstein's theory of relativity (E=mc^2). This allows for a small amount of mass to be converted into a large amount of energy, as seen in nuclear reactions.
Within which type of system is neither the total mass nor the total energy conserved?
In an open system, neither total mass nor total energy is typically conserved. This is because open systems can exchange matter and energy with the surrounding environment, leading to changes in mass and energy within the system itself.
When did albert Einstein invent e equals mc2?
In the beginning of the 20th century. He proposed mass-energy equivalence in 1905, and set out to mathematically express this. E = mc2 shows that energy can be converted into mass, and mass into energy. Thus, we no longer say that mass is conserved, or energy is conserved. But rather, we say that mass-energy is conserved.
What is conserved in physical changes?
Mass and energy
What is conserved during a reaction?
Both mass and charge
What would happen if matter mass and energy were not conserved?
If matter, mass, and energy were not conserved, it would violate fundamental laws of physics and lead to unpredictable and chaotic behavior in the universe. This could result in unstable systems, unexpected interactions, and potentially the breakdown of the laws that govern our understanding of the universe.
Is energy conserved in a nuclear reaction?
Yes. Basically, energy is ALWAYS conserved. The popular saying, that in a nuclear reaction mass is converted to energy, is plainly wrong, since both mass and energy are conserved. Read about "mass deficit", for example in the Wikipedia, for more details.
In a nuclear reaction WHAT does not have to be conserved?
While overall ENERGY has to be conserved, MASS does not. In a nuclear reaction mass can be converted into energy so the mass of the products may be less than the mass of the reactants. The difference in mass is converted into energy as Einstein's equation describes (E=MC squared). In a chemical reaction MASS has to be conserved.
How living systems follow the law of conservation of mass and energy?
Living systems follow the law of conservation of mass and energy by taking in nutrients and energy from their environment to sustain their growth, reproduction, and metabolism. Waste products like carbon dioxide and heat are released in the process to maintain the balance of mass and energy in the system. This ensures that the total mass and energy within the system remains constant over time.
Which is not conserved mass acceleration energy momentum?
Energy is not conserved in some situations, especially in processes involving non-conservative forces like friction or air resistance. The conservation of mass, acceleration, and momentum are fundamental principles in physics.
What is conserved when one balances a chemical equation?
When balancing a chemical equation, the number of each type of atom on the reactant side must be equal to the number of each type of atom on the product side. Mass and charge are conserved during a chemical reaction as well.
Is energy is conserved when an atom emits a photon of light?
Energy is ALWAYS conserved. The appropriate sum of mass and energy is always conserved. If an atom emits a photon, the atom has less energy/mass, and the universe minus that atom has more energy/mass. It's like carrying some energy from here to there.
