Question
I am very new to the study of chemistry so I hope that you can help. What substances are cold but not as extreme as dry ice
You don't have many choices. You can freeze water that contains different levels of salts to get to -20 to -30 C. That is what makes ice cream making work. Anything else that you freeze like ethanol has the bad property of melting chemical and flammability. After frozen water, dry ice is the next in line by temperature of things that can easily be used.
