Question

What is a star? Group of answer choices A ball of gas that reflects light from another energy source. A bright point of light visible in Earth’s atmosphere. A hot ball of gas that produces energy by burning gases. A hot ball of gas that produces energy by combining atoms into heavier atoms. A hot ball of gas that produces energy by breaking apart atoms into lighter atoms.

Answer 1

Answer: A hot ball of gas that produces energy by combining atoms into heavier atoms.

A STAR can be defined as a luminous celestial body, made up of plasma (particularly hydrogen and helium) and having a spherical shape. They are small luminous dot appearing in the cloudless portion of the night sky, especially with a fixed location relative to other such dots.

They produce their energy by varieties of nuclear fusion reactions that take place in the cores of stars, that depend upon their mass and composition.

Answer 2

A hot ball of gas that produces energy by combining atoms into heavier atoms.

Step-by-step explanation:

A star is a huge glowing ball of hot gas, mainly hydrogen and helium. Stars fuse atoms in their core to produce heat and light energy. An example of a star is the sun, which slams hydrogen atoms together under high heat and pressure resulting in a much heavier atom, a helium atom. Very heavy elements are made in massive starts when they die.
