Answer 1:
I'm not familiar with a temperature format with
the degree symbol in front. Usually temperature is
written as, say, 10 degrees C (or F) with the
little circular symbol substituting for the
"degrees" before the C. Degrees, as you know, are
the units that temperature is divided into and the
C or F determine which temperature scale you are
using.
It's quite possible that a chemistry or physics
textbook would have a letter with what seems to be
a degree symbol after, but I think that would be
denoting something other than temperature. In a
chemistry text book, for example, it might mean a
quantity that is measured at a "standard" state. A
"standard" state usually means 25 (or 0) degrees C
and 1 atmosphere of pressure. Often it is used
when a quantity changes with temperature and
pressure. What properties do you think would
change if you changed the temperature and/or
pressure of a sample of water?
Here's a Wikipedia website that has some more
"info" about the temperature scales:

As an aside, when you learn about the absolute
temperature scale, also known as Kelvin, you
usually omit the "degrees" and say, for example,
273.15 K = 0 degrees C. |
