Question

Which statements describe properties of stars? Check all that apply.
Stars produce energy through nuclear fusion.
Stars produce energy through gravity.
Stars are massive objects composed of gas.
Stars are solid objects that we could stand on.
Stars are composed primarily of hydrogen and helium.
Stars are composed primarily of liquids such as water.

Answer 1

Answer:

• Stars produce energy through nuclear fusion.
• Stars are massive objects composed of gas.
• Stars are composed primarily of hydrogen and helium.

Explanation:

Stars are massive objects that have a large gravitational field, which drives the star to contract on itself, which is why fusion occurs: in the center of the star the nuclei of atoms are already so close due to gravity and high temperatures that bind. This is what is called nuclear fusion and is the energy source of a star.

On the other hand yes, the main elements of a star are hydrogen and helium (two hydrogen nuclei fuse to make helium), this makes the star mainly a huge ball of gas so there is no solid surface where you can stand on.

And about water on a star, that is not possible. Temperatures on stars are very vey high that watter could not exist in a liquid form on them.

Answer 2

• The statements that give description about gas from the question  are;

Stars produce energy through nuclear fusion.

Stars are massive objects composed of gas.

Stars are made primarily of hydrogen as well as helium.

• Stars can be regarded as  massive objects which contains  large gravitational field, that  drives the star so as to contract on itself, as a result of this  fusion occurs

• At  center of the star there is a nuclei of atoms which are already so close due as a result of  gravity as well as high temperatures that bind.

• the main elements that star is made of are hydrogen and helium, i.e there is fission of two hydrogen nuclei  along with  helium, As result of this  the star is  mainly a huge ball containing gases

• There is no water on a star, since there is high temperature on the star and cannot allow water to stay.

• Stars can be regarded as body which is composed of  hydrogen as well as  helium, these are been  packed so densely in a star

• In the  star's center there is great pressure that  initiate nuclear fusion reactions.

• Nuclear fusion reaction is the one whereby  the nuclei of two atoms comes together to create a new atom.

Therefore,  statements that  describe properties of stars here Stars produce energy through nuclear fusion is that Stars are been regarded as  massive objects  which is encompassed  gas.
