The Sun and the stars glow because of the presence of which state of matter in them?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → Plasma
Plasma is a state of matter made of super-energetic, super-excited particles in the form of ionised gases. The high temperature in the Sun and the stars produces plasma, which makes them glow; a neon sign bulb also glows because of plasma.
