In need of more practice questions for HSC Physics Module 8: From the Universe to the Atom? Well, luckily we’re here to help you out! Just in case you missed it, we broke down Module 8 in this article here!

We’ve structured the From the Universe to the Atom module by breaking it up into five parts (based on each inquiry question). So today we’re going to have a look at:

  • Origins of the Elements
  • Structure of the Atom
  • Quantum Mechanical Nature of the Atom
  • Properties of the Nucleus
  • Deep Inside the Atom

Let’s dive into these Physics Module 8: From the Universe to the Atom practice questions!

Origins of the Elements

Question 1

Many members of the public believe that the Big Bang was an explosion that resulted in mass and energy being catapulted into space. Explain what is wrong with this belief.

 

Investigate the processes that led to the transformation of radiation into matter that followed the ‘Big Bang’

Question 2

Explain the consequence of special relativity in relation to the equivalence between mass and energy.

 

Analyse and apply Einstein’s description of the equivalence of energy and mass and relate this to the nuclear reactions that occur in stars (ACSPH031)

Question 3

Using a H-R diagram, where would you find the dullest stars?

 

Investigate the HertzsprungRussell diagram and how it can be used to determine the following about a star:

  • characteristics and evolutionary stage
  • surface temperature
  • colour
  • luminosity

Question 4

During the process of transitioning from a main sequence star to a red giant a “helium flash” occurs. Explain the reason why this helium flash occurs.

 

Investigate the types of nucleosynthesis reactions involved in Main Sequence and Post-Main Sequence stars, including but not limited to:

  • proton–proton chain
  • CNO (carbonnitrogenoxygen) cycle

Question 5

The proton-proton chain reaction occurs mainly in stars around the size of our sun or smaller. Why is this so?

 

Investigate the types of nucleosynthesis reactions involved in Main Sequence and Post-Main Sequence stars, including but not limited to:

  • proton–proton chain
  • CNO (carbonnitrogenoxygen) cycle

Question 7

How was Thomson able to determine the charge to mass ratio for cathode rays. Use mathematical equations as well as diagrams to help explain.

 

Investigate, assess and model the experimental evidence supporting the existence and properties of the electron, including:
