Question

The sun and the stars are made of: CO2, He & H20 O H2, CH4 H2, He & CO2 О Н., Не ​

Answer 1

Answer:

Critical temperature ∝ van der Waal constant 'a'

Maximum 'a'⇒ gas with maximum T

C

⇒ easiest liquification =NH

Answer 2

Answer:

Why don't we know how long it takes for a photon to travel outward from the center of the sun? For one thing, scientists can't see into the core to track a photon from its birth. Instead, they must rely on models that follow the infamous "drunkard's walk" problem. According to this scenario, the distance a drunken person travels while making random left and right turns is their typical step size times the square root of the number of steps taken. For a randomly traveling photon in the solar center, this depends on what is used for the mean free path (or average distance travel) of radiation. These numbers range from 4,000 years to millions of years, though most solar scientists tend to rely on 170,000 years.
