Dear Ms O’Dwyer

I found on the internet that Charles Thiorier discovered dry ice in 1834. He found dry ice in a liquid carbon dioxide cylinder.

I like science because it is great! I like dry ice too. I also want to know how dry ice can melt without becoming liquid and who was the frist person to make dry ice.

Kind Regards,
Poonnapa

Sublinimation is a process of solid NOT getting to a liquid. It’s a process of solid getting to a GAS!
The temperature should be -75 degrees in the refrigerator for it to be a solid.

The science experiment that we experienced was SO cool!
Thank you for letting us see that great thing. I’d like to try it again, too!
I have a question for you and others. Who first discovered this type of Science?

I’ll wait for your kind reply.

Sincerely,
Diana
