Answer #1

We have equation of state

where PC central pressure of earth so we can write

where TC = central temperature of earth.

now we have PC=

m=mproton/2=0.84*10-27 kg

constant density

  

WHERE R =696,340 km PUTTING VALUE WE GET

density of su as 1.41 g/cm³ now by putting all value in above equation we get

TC 1.2*107 k

The Missing Source of the Sun’s Energy: As photons from the Sun’s interior leak away, they are replaced with new ones. But what is the source of those new photons? In the core of the Sun, the gas is hot and thermodynamics tells us that the thermal energy per unit volume (the thermal energy density) stored in the motion of the gas particles is Ethermal = 3P/2. Recall from the previous question** that a photon created a the center of...
