Cool carbon dioxide (do you get the joke?)
It began in Lab_13. It was a foggy morning and it was cold. We were on our way to the school for the Lab_13 committee meeting.
In the middle of our meeting suddenly a mysterious figure appeared through the door. She was clutching a thermos flask full of something unexpected and freezing. We asked what the temperature of it was and there was a reply of “-78.5°C.”At this our brains exploded!
Then Carole plopped it into her coffee and gas rose up, bubbles started to do what bubbles do best: bubble! We wondered why it didn’t turn into a liquid. The answer was carbon dioxide ice was sublimating (turning into a gas and skipping the liquid state).
You could use it in a balloon instead of blowing it up. Hope you enjoyed this story.
