Hi I tried cooling down some 91% isopropyl alcohol with dry ice. After a few minutes, the alcohol became a thick gel. I am wondering what is going on there, thanks.
Alcohol gel cooled with dry ice works by utilizing the sublimation process of dry ice. As the dry ice evaporates, it absorbs heat from the alcohol gel, cooling it down significantly. This is because dry ice has a temperature of -109.3°F (-78.5°C) and is much colder than regular ice. The alcohol gel is able to reach a lower temperature than it would with regular ice, making it an effective cooling method.
Yes, alcohol gel cooled with dry ice is generally considered safe to use. However, it is important to handle dry ice with caution as it can cause burns if it comes into direct contact with skin. It is also important to ensure proper ventilation when using dry ice as it releases carbon dioxide gas. As with any chemical or substance, it is important to follow safety precautions and handle it with care.
Alcohol gel cooled with dry ice has several benefits. It can create a much colder temperature than regular ice, making it an effective method for keeping items cold or for use in scientific experiments. It also does not melt like regular ice, making it a more convenient option for long-term use. Additionally, dry ice is non-toxic and odorless, making it safe for use in food and beverage cooling.
Not all types of alcohol gel are suitable for use with dry ice. It is important to check the label of the alcohol gel to make sure it is safe for use with dry ice. Some types of alcohol gel may contain substances that could react with dry ice and cause harm. It is best to use alcohol gel specifically labeled as safe for use with dry ice.
The duration of the cooling effect of alcohol gel cooled with dry ice will depend on various factors such as the amount of dry ice used, the type of alcohol gel, and the surrounding temperature. Generally, it can stay cold for several hours, making it a suitable option for outdoor events or scientific experiments that require prolonged cooling. However, it is important to regularly check the temperature and add more dry ice if needed to maintain the desired level of coldness.
