Briefly describe how you can use spectra as evidence of nuclear fusion in stars.

Spectra can be used as an evidence that nuclear fusion occurs in the star through the ability of the elements generated to absorb light at specific wavelength.

The internal part of the star is made up of hydrogen gas, with a little helium.

The helium atom is formed through the nuclear fusion reaction that occurs in the core of the star.

Nuclear fusion reaction involves the combination of two or more atoms which leads to the formation of a new atom with the emission of great energy. This reaction leads to formation of helium elements in the core of the stars.

To detect if nuclear fusion reaction is occurring in the stars, a spectrum is used.

Because each element emits or absorbs light only at specific wavelengths, the chemical composition of stars can be determined using a spectrum.

d.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.
