The solar corona is a very hot atmosphere surrounding the visible surface of the sun. X-ray emissions from the corona show that its temperature is about . The gas pressure in the corona is about . Estimate the number density of particles in the solar corona.
The number density of particles in the solar corona is .
Given : Temperature of X-ray emissions :
The gas pressure is :
Theory used :
Number density is given by The ideal gas law is given by we'll rewrite the equation of Ideal Gas Law for in the form
If we know the number of molecules , we obtain the number of moles by taking Avogadro's number
Now put the expressions for in number density equation we get: Now we put the values for into this equation to get the number density
