How do you explain nuclear fusion to a child?
Nuclear fusion happens when the nucleuses (or nuclei) of two atoms collide to create a tremendous amount of energy. Most nuclear fusion happens in stars, such as our sun. Creating nuclear energy through nuclear fusion here on Earth is very difficult because it requires too much heat in order for it to occur.
What is fusion kid definition?
the act of fusing or joining together.
What is fusion energy for kids?
Fusion occurs when two or more atoms are joined together to make a larger atom. Stars get their power from nuclear fusion. Deep inside a star, hydrogen atoms are constantly being converted by fusion into helium atoms. It’s this process that generates the light and heat energy given off by the stars including the Sun.
What is fusion reaction in simple words?
In a fusion reaction, two light nuclei merge to form a single heavier nucleus. The process releases energy because the total mass of the resulting single nucleus is less than the mass of the two original nuclei. The leftover mass becomes energy.
What describes nuclear fusion?
Nuclear fusion is a reaction in which two or more atomic nuclei are combined to form one or more different atomic nuclei and subatomic particles (neutrons or protons). The difference in mass between the reactants and products is manifested as either the release or the absorption of energy.
What is the process nuclear fusion?
nuclear fusion, process by which nuclear reactions between light elements form heavier elements (up to iron). In cases where the interacting nuclei belong to elements with low atomic numbers (e.g., hydrogen [atomic number 1] or its isotopes deuterium and tritium), substantial amounts of energy are released.
What is fusion with example?
The definition of fusion is the act of melting or blending two or more separate things into one. An example of fusion is creating a dinner that combines Indian and Japanese elements.
Why is nuclear fusion important?
Abundant energy: Fusing atoms together in a controlled way releases nearly four million times more energy than a chemical reaction such as the burning of coal, oil or gas and four times as much as nuclear fission reactions (at equal mass). Its major by-product is helium: an inert, non-toxic gas.
How is nuclear energy kids?
To produce nuclear power, you need uranium atoms. These are found in uranium, a mineral we can dig up from the ground. When you split a uranium atom into two smaller atoms, it releases heat. This heat is used to produce steam, which turns enormous turbines in a nuclear plant.
What is nuclear fusion equation?
An important fusion reaction for practical energy generation is that between deuterium and tritium (the D-T fusion reaction). It produces helium (He) and a neutron (n) and is written D + T → He + n. To the left of the arrow (before the reaction) there are two protons and three neutrons.
How do you get nuclear fusion?
Fusion fuel – different isotopes of hydrogen – must be heated to extreme temperatures of the order of 50 million degrees Celsius, and must be kept stable under intense pressure, hence dense enough and confined for long enough to allow the nuclei to fuse.
