Mini-Quiz: Antimatter

by Ron Kurtus (updated 8 February 2022)

Take this Mini-Quiz to check your understanding of the lesson material.

1. What would be the makeup of anti-carbon dioxide?

Anti-carbon dioxide would consist of one anti-carbon atom and two oxygen atoms

It is impossible for anti-carbon dioxide to exists

Anti-carbon dioxide would consist of one anti-carbon atom and two anti-oxygen atoms

2. What would happen if antimatter was placed container made of standard matter?

It would create a gas that would expand the container

It would interact with the container material, resulting in a great amount of energy being released

Nothing, because placing antimatter in a container is the way to store it

3. How could we tell if another part of the Universe consisted of antimatter?

Unless the objects collided with matter, it would be impossible to tell that it was antimatter

Light from antimatter goes in the opposite direction

By studying chemical reactions in that part of the Universe

If you got all three correct, you are on your way to becoming a Champion in Physics. If you had problems, you had better look over the material again.

Consider the impossible
