What explains why the Sun maintains its size and shape?

Explanation: The Suns own weight keeps itself together and keeps its size and shape. all things have gravity. in this case, the sun keeps it shape with balancing its gravity with the pressure.

What forces hold the sun together?

The Sun’s enormous mass is held together by gravitational attraction, producing immense pressure and temperature at its core.

What keeps the sun stable?

As it turns out, the Sun is kept stable by its internal pressure. Within the Sun, therefore, pressure creates an outward force, from the high-pressure core to the low-pressure surface. This is in contrast to gravity, which creates an inward force.

What holds the sun to stay in the sky?

If you mean what holds hydrogen of the sun together, it is the gravitational energy that it derives from its huge mass. On the other hand, fusion is producing energy at its core which creates an outward radiation pressure which balances the gravitational pull. This dynamics help in creating a stable Sun.

What is the hottest type of sun?

One of the best known examples is Eta Carinae, located about 7,500 light-years from the Sun. Eta Carinae could be as large as 180 times the radius of the Sun, and its surface temperature is 36,000-40,000 Kelvin. Just for comparison, 40,000 Kelvin is about 72,000 degrees F.

Is green or blue fire hotter?

Blue flames have more oxygen and get hotter because gases burn hotter than organic materials, such as wood. For example, the element lithium will produce a pink flame, while the element tungsten will produce a green flame.

What burns a green flame?

Because each element has an exactly defined line emission spectrum, scientists are able to identify them by the color of flame they produce. For example, copper produces a blue flame, lithium and strontium a red flame, calcium an orange flame, sodium a yellow flame, and barium a green flame.

Are green flames dangerous?

Green flame can be caused by copper salts or corroded copper parts contaminating the flame with copper ions. This can “naturally” happen, and the minute amount of copper is harmless. However if someone intentionally put larger amount of toxic copper salts there, that might be dangerous.

Does salt burn green?

Basic table salt burns yellow. The flames coming off of copper are bluish-green. Potassium burns violet. With all of these salts burning different colors, all teachers have to do is line them up in the order of colors in a rainbow — red, orange, yellow, green, blue, indigo and violet.

Why are Flames different colors?

The colors of a flame are caused by bits of wax molecules that didn’t get completely reacted. These glow a certain color when they get to be a certain temperature. Since different parts of the flame have different temperatures, these bits of wax molecules make those areas of the flame glow with different colors.

How do you make a blue flame?

Copper chloride: Makes a blue flame….The Process:

  1. Melt the candle wax in a double boiler or old pot.
  2. Take out the number of paper cups that you are planning to use and fill them with a ¼ inch of your chosen chemical.
  3. Pour the melted wax into the cup, making sure that it completely covers the chemical.
