Why are white stars hotter?

Most white stars are going to be hotter and more massive than our Sun. This means they’re more luminous and use their hydrogen fuel up more quickly. Of course, another kind of white star are the white dwarfs. These were once stars like our Sun, but they used up all the hydrogen fuel in their core.

Q. What makes a star twinkle?

As light from a star races through our atmosphere, it bounces and bumps through the different layers, bending the light before you see it. Since the hot and cold layers of air keep moving, the bending of the light changes too, which causes the star’s appearance to wobble or twinkle.

Q. Why does a star die?

Stars die because they exhaust their nuclear fuel. Really massive stars use up their hydrogen fuel quickly, but are hot enough to fuse heavier elements such as helium and carbon. Once there is no fuel left, the star collapses and the outer layers explode as a ‘supernova’.

Q. Do dead stars glow?

After a star dies, there is still some residual heat left over. That heat makes the star (white dwarf or neutron star) glow, even though it is not producing any energy. Eventually, the star cools off and does indeed simply become a hunk of ash, which we call a “black dwarf.”

Q. Is White Fire Possible?

You can make fire burn with a pure white flame. White is an elusive fire color because the fuel that supports a flame burns with its own characteristic spectrum. But, with a little chemistry know-how, you can get white fire.

Q. Does a black flame candle exist?

As the name implies, the candle, when lit, burns with a black flame, gives off NO light and is full of dark magic. Today we’ll be making an electric version of the famous Black Flame Candle from Hocus Pocus and I promise, the only thing this candle will raise when lit is the amount of light in the room.

Q. Why our shadow is black?

a shadow is caused by an object blocking light so that it does not reach a surface. The area in shadow appears black because there is no light falling on it—-it appears dark. In fact most shadows are not totally black because light usually bounces around the obstruction off other objects.

Q. Which thing has no shadow?

Transparent objects cannot form a shadow. They are only formed in opaque or translucent objects. If we take a glass slab, no shadow is formed because it allows light to pass through it.

Q. Why do shadows appear?

Outside, people make shadows when they block light from the sun. Your body blocks some of the sun’s light, causing a shadow to form in front of you. The shadow takes on the shape of your body. When the sun is in front of you, the shadow forms behind you.

Q. How do shadows appear?

Shadows are made by blocking light. If an opaque (solid) object gets in the way, it stops light rays from traveling through it. This results in an area of darkness appearing behind the object. The dark area is called a shadow.
