Best answer: What is the law of conservation of mass and energy how is it relevant to nuclear fusion in the sun?

HOW IS THE RELEVANT TO NUCLEAR FUSION IN THE SUN? The law of conservation of energy states “energy cannot be created or destroyed, only converted from one form to another”, mass and energy are almost the same thing.

Is law of conservation of mass applicable to nuclear reactions?

What about the laws of conservation of mass and conservation of energy? … A: No, the laws still apply. However, it’s more correct to say that the sum of mass and energy is always conserved in a nuclear reaction. Mass changes to energy, but the total amount of mass and energy combined remains the same.

Why nuclear reaction does not follow law of conservation of mass?

By the equation given by Einstein, E=mc^2, you can see that mass can be converted to energy. So, the law of conservation of mass is not applicable in nuclear reactions because some mass gets converted to energy. Mass and energy are interconvertable.

What is nuclear fusion how it is useful to explain the energy of Sun?

Depiction of the deuterium (D) and tritium (T) fusion reaction, which produces a helium nucleus (or alpha particle) and a high energy neutron. Nuclear Fusion reactions power the Sun and other stars. In a fusion reaction, two light nuclei merge to form a single heavier nucleus.

How is energy produced in the Sun and other normal stars quizlet?

In the hot cores of stars, the nuclei can get close enough to fuse together and release energy. The Sun generates its energy by converting hydrogen into helium by a process called nuclear FUSION. … Nuclear fusion reactions occur in the hottest, densest part of the Sun and other stars – in their central core.

Can you break the law of conservation of mass?

There is no law of conservation of mass. Depending on whether you are a glass half-full or glass half-empty kind of person this means that you can never break it or you only break it.

What is the difference between the law of conservation of mass and matter?

Matter is anything that has mass and takes up space. … Matter can change form through physical and chemical changes, but through any of these changes, matter is conserved. The same amount of matter exists before and after the change—none is created or destroyed. This concept is called the Law of Conservation of Mass.

What is the importance of the law of conservation of mass?

The law of conservation of mass is important because it allows us to predict the amount of product formed in a chemical reaction, as well as the amount of consumed reactant.

Can the conservation of energy be violated?

To sum it up, yes, conservation of energy can be violated, but nature makes sure it is always within the limits of uncertainty. In other words, the energy must be returned, and the books set straight pretty quickly.

Is the sun a fusion reaction?

The Sun is a main-sequence star, and thus generates its energy by nuclear fusion of hydrogen nuclei into helium. In its core, the Sun fuses 500 million metric tons of hydrogen each second.

Is fusion a chemical reaction?

While chemical reactions – such as the rusting of metal or the burning of wood – involve the redistribution of electrons between atoms, nuclear reactions involve the redistribution of nucleons. … Alternatively, in the proton-proton nuclear fusion reaction, the nuclei of two hydrogen atoms merge together to form helium.

What type of reaction is fusion?

Nuclear fusion is a type of nuclear reaction where two light nuclei collide together to form a single, heavier nucleus. Fusion results in a release of energy because the mass of the new nucleus is less than the sum of the original masses.
