Why can the fusion of iron into heavier elements not support a star?
The fusion of iron into heavier elements cannot support a star because it requires more energy than it produces, leading to a loss of energy and the collapse of the star.
What makes up a star and how does it contribute to its formation and characteristics?
Stars are made up of mostly hydrogen and helium gas, along with trace amounts of other elements. The force of gravity causes these gases to come together and form a star. As the gases compress and heat up, nuclear fusion reactions occur in the star's core, producing energy and light. This energy counteracts the force of gravity, keeping the star stable and allowing it to shine. The size, temperature, and lifespan of a star are determined by its mass and composition.
What are the most numerous elements?
The most numerous elements in the Earth's crust are oxygen, silicon, aluminum, and iron. These elements make up the majority of the Earth's crust by mass.
What are the four elements that make up over 95 percent of the body in most of energy?
The four elements that make up over 95 percent of the human body are oxygen, carbon, hydrogen, and nitrogen. These elements are fundamental in forming essential molecules like proteins, carbohydrates, and fats, which are crucial for energy production and bodily functions.
Why is the presence of elements heavier than helium in stars very important?
The presence of elements heavier than helium in stars is important because they provide crucial information about the star's age, composition, and evolutionary history. These heavier elements, also known as metals, are created through nuclear fusion processes in the cores of stars and are dispersed into space when the star dies. By studying the abundance of these elements in a star, scientists can gain insights into its formation and evolution.
What two elements make up the most matter in a star?
Hydrogen and Helium
What are elements called that make up a star?
Stars are composed mostly of hydrogen and helium.
What are the two main gases that make up a young star?
The two main gases that make up a young star are hydrogen and helium. These elements were formed during the Big Bang and are the most abundant elements in the universe.
What element make up the mystery star?
The mystery star is made up of a variety of elements, such as hydrogen, helium, carbon, oxygen, and trace amounts of other elements like iron, silicon, and nitrogen. These elements are formed through nuclear fusion processes that occur in the star's core.
What two elements make up the most of matter in a star?
The exact mix is different depending on the star's age and size, but hydrogen and helium are always the two most prevalent elements.
What two elements make up most of the matter in star?
The exact mix is different depending on the star's age and size, but hydrogen and helium are always the two most prevalent elements.
What are the main forces that make up a star?
Objects are not made of forces. A star is made of hydrogen, helium and, later in its life, heavier elements.
How does spectral analysis allow scientist to know what elements make up a star or rock layer?
It allows scientists to see how hot that star is and what spectrum it has.
Carbon and what other element make up a white dwarf?
Carbon and oxygen are the two main elements that make up a white dwarf star. These elements are the end products of nuclear fusion in the core of the star before it exhausted its nuclear fuel and collapsed to form a white dwarf.
Can scientists analize the elements of a star?
Scientists can assess which elements are present in the star, by looking at the light it gives off and breaking this light down into the different colours that make up the total colour. They look at the spectrum given off. The different elements present in the star cause different light wavelengths (or colours) to be emitted.
What elements make up elements of sugar?
Carbon, hydrogen and oxygen are the only elements that make up sugars.
What is produced within a star's core?
New elements - helium always, heavier elements often (up to iron) and heavier than that if the star explodes.
