Question: What is the source of energy for the sun Brainly?

What is the source energy of sun?

The sun generates energy from a process called nuclear fusion. During nuclear fusion, the high pressure and temperature in the sun’s core cause nuclei to separate from their electrons. Hydrogen nuclei fuse to form one helium atom. During the fusion process, radiant energy is released.

What is the source of energy of sun and star?

For the Sun and other normal main-sequence stars, the source of energy lies in the conversion of hydrogen to helium. The nuclear reaction thought to occur in the Sun is called the proton-proton cycle.

What is the source of energy for sun and stars What are the conditions needed?

Nuclear Fusion

The Sun is Earth’s major source of energy, yet the planet only receives a small portion of its energy and the Sun is just an ordinary star. Many stars produce much more energy than the Sun. The energy source for all stars is nuclear fusion.

What is the most important energy source?

One of the most important sources of energy is the sun. The energy of the sun is the original source of most of the energy found on earth. We get solar heat energy from the sun, and sunlight can also be used to produce electricity from solar (photovoltaic) cells.

Is star a source of heat?

Stars are a source of heat, as are planets which radiate heat into space. Jupiter, for instance, radiates more heat than it absorbs.

What is the main source of a star’s light and heat?

The source of their energy is nuclear reactions going on deep inside the stars. In most stars, like our sun, hydrogen is being converted into helium, a process which gives off energy that heats the star. The inside is actually millions of degrees, extremely hot!

Which is known as the biggest stars in the universe?

The largest known star in the universe is UY Scuti, a hypergiant with a radius around 1,700 times larger than the sun.

How energy from the sun is passed to you?

humans get energy indirectly from the sun, but directly through plants. plants get energy from the sun through photosynthesis, and we eat the plants.

Can humans absorb energy from the sun?

But the ability to capture the energy in sunlight isn‘t new to humans. In fact, it’s coded in our DNA. The human body is capable of building specialized proteins that transform light energy into chemical energy. … Most life forms have evolved to capture and use this energy for various purposes.
