In the attached excerpt from a science worksheet, what's the appropriate approach to the temperature (precisely ELI and the C) without punctuation in the first instance and with in the second? The degree sign appears to be spaced from the number and attached to the C.
There are two occurrences of the abbreviation C for Celsius in your example. The first occurs in the midst of a sentence and is not followed by a period; and the second occurs at the end of a sentence and is followed by a period. The occurrence of C without a period in the midst of a sentence tells us that this print text is not using a period with the abbreviation C for Celsius. In other words, the period that follows after the second C is just for the sentence and is not for the abbreviation.
Thus, we need an ELI with all occurences of the abbreviation C for Celsius.
