Answer:

B. An atom is a solid sphere

Explanation:

The idea that the atom was a solid sphere paved back to the first atomic model in the <em>19th century</em> theorized by <em>John Dalton</em>. According to him, an atom is <u>intact and hard and cannot be broken down or divided</u>.

However, many scientists continued to research and it was found that <em>the atom was not actually a solid sphere.</em> It was made up of<em> protons (positively-charged), electrons (negatively-charged) and neutrons (neutrally-charged). </em>This invalidated Dalton's solid sphere model.

The words to fill up the crossword titled, "The Hero's Journey" are:

Across:

  • 1. Monomyth.
  • 6. Threshold.
  • 7. Shape shifter.
  • 10. Archetype.

Down:

  • 2. Antithero.
  • 3. Atonement.
  • 4. Talisman.
  • 5. Mentor.
  • 8. Abyss.
  • 9. Hero.

<h3>What are the words in the crossword puzzle?</h3>

The journey that a hero goes on is a monomyth and the point of entering or beginning is a threshold.

When a creature can transform into another shape or thing, they are shape shifters and the original pattern of something is its archetype.

When a protagonist lacks the properties of a hero, they are antiheroes but when they are admired for brave deeds, they are heroes.

Correcting a wrong that we did is atonement and when an object has a powerful influence on others it is likely a talisman. Mentors are wise people who we trust to counsel us.

kiruha [24]
<span>D) the Mass of water needs to be in a closed system to control the boiling. With an open system, you can no longer measure the water vapor output and be sure that the water vapor in the bottle is equal to the water vapor in the air or beyond. It is only through the closed system that you can measure the volume, the mass difference and ensure that both are in equilibrium</span>
