This can make the thermometer show the results more slowly and less accurately. High boiling point and very low freezing point 4. Mercury is difficult to clean and it can easily contaminate other surfaces after a thermometer breaks. They both have advantages and disadvantages: A mercury-in-glass thermometer can measure high temperature (up to 357 0C, the boiling point of mercury; and its freezing point is -39 0C). It is true that mercury can be a dangerous chemical, though there is some dispute about how dangerous it is if properly cleaned up. The Mercury Thermometer, on the other hand, is more durable under general conditions. 2. slow response . 1.
