 We have a CBL to act as our thermometer. So it's reading the temperature of this ice water bath. And I hope you can see the decimal right there. It's actually 0.1 degrees Celsius. What I want you to do is observe what happens when we add salt to our solution. You can see that we have lowered the temperature by 4.3, 4.5, 4.7, 5.636 degrees. So we were able to lower the temperature by 6 degrees by adding the salt.
