Question
Chapter 2, Problem 1RQ
To determine
The reason why the astronomers consider the space between the planets to be a vacuum in comparison with the atmosphere near the sea level.
Expert Solution & Answer
Answer to Problem 1RQ
The astronomers believe that the space between the planets is a vacuum that is related to the atmosphere near the sea level due to the very low density of matter there.
Explanation of Solution
The interstellar space in the solar system hardly consists of one atom per liter when compared to the air at the sea level which has around
The density of atoms in the space between the planets or stars is very low when related to the air at the sea level and is very close to a vacuum condition. It is because of this reason that the astronomers consider the space between the planets as a region of vacuum.

10.8 Numerical Dating with Radioactivity
■ Explain the principle of radiometric dating, including half-life, parent isotope,
and daughter product.
Radioactivity has provided a reliable means for calculating the numerical (absolute) age of
rocks, a procedure called radiometric dating. Radioactive isotopes, such as uranium-238,
emit particles from their nuclei that we call radiation. Ultimately, the process of decay…
