Antimatter

The video explains that for every particle of ordinary matter, there is a corresponding antiparticle with the same mass but opposite charge. When a particle, like an electron, collides with its antiparticle, a positron, they annihilate each other, releasing pure energy. This process can also occur in reverse.

What is the relationship between ordinary matter and antiparticles?

• Antiparticles are heavier than ordinary matter.

• Antiparticles have no relation to ordinary matter.

• Each particle of ordinary matter has a corresponding antiparticle.

• Antiparticles are a type of ordinary matter.

What is a key characteristic of antiparticles compared to their corresponding particles?

• They are larger in size.

• They have the opposite charge.

• They have the same charge.

• They have a different mass.

What happens when an electron collides with a positron?

• They annihilate each other, releasing energy.

• They merge into a larger particle.

• They form a new particle.

• They bounce off each other.

What is the result of the annihilation of a particle and its antiparticle?

• A new particle is created.

• Energy is released.

• They disappear without a trace.

• They become stable.

Can the annihilation process between particles and antiparticles occur in reverse?

• Only under specific conditions.

• It depends on the type of particles.

• Yes, it can occur in reverse.

• No, it is a one-way process.
