Does Dry Ice Cool Better than Regular Ice? Find Out Using Raspberry Pi #piday #raspberrypi @Raspberry_Pi

via Jeremy Morgan

I saw an advertisement for dry ice claiming it cools 5 times better than wet ice. Out of curiosity I had to know if this were true, or at the very least see how much better dry ice performs. I thought I’d gather up a Raspberry Pi and some sensors and find out, using some techniques from my Hands on Internet of Things course released recently.

 

This is the first thing I wondered. Does it keep it 5 times colder? Does it keep it cool 5 times longer? The claim is still a bit unclear, but based on my results it appears it keeps it close to 5 times colder, for about the same amount of time.

What I did was take a couple coolers, filled one with Dry Ice and one with wet ice, sealed them up and measured them for a few days.

  1. Dry Ice is dangerous because if you had enough of it and were locked in a freezer or a box truck with it, it basically replaces the air with carbon dioxide so you would not be able to breathe.

    Quote – Dry ice is classified by DOT and IATA as a “miscellaneous” hazard, Class 9. Dry ice is considered hazardous during transportation for the following reasons: Explosion hazard: Dry ice releases a large volume of carbon dioxide gas as it sublimates.

    If you see a placarded vehicle with Class 9 on the four diamonds, it is carrying about 1,001 or more pounds of dry ice.
