Question: 47

What is the coldest possible temperature in the universe?

View the answer

-273°C. This is called “Absolute Zero”, the point at which particles stop moving. Since temperature and heat is a measure of how much energy a particle has to jiggle with, and you can move any less than not moving at all, this is the coldest possible temperature anything can be.

School Comments View All

I just wanted to pass on how much the staff and students really enjoyed it and how perfect it was to launch our science week activities. The students were enthralled, educated and entertained – a perfect trifecta!

-Caulfield Grammar School – Big Science Big Fun

Thanks so much for presenting at our school on Monday. Our students enjoyed the show.

-Greenvale Primary School – Big Science Big Fun

Fizzics Education curated a thoughtful and hands-on experience for the children, incorporating practical, skill-based learning activities and followed by a science presentation at the end of the event involving liquid nitrogen. This was delivered safely and effectively, capturing both the children and the parents for the duration of the presentation.

-Macquarie Bank – Family Fun Day

Fizzics Education ran a show today at our school and it was wonderful. He was a great facilitator and the show was age appropriate and well done.

-Mount Zion Early learning centre – Little Science Big Fun

Welcome!
