I think temperature and heat might be similar. But how?
That is BTU = Degrees Fahrenheit.

Sorry, Bob. You're dead wrong on this one.


Hi Dave:
Okay........... I agree, most likely wrong. Im not sure about the dead
part, although I felt like sunday morning. Thats what I was wondering.
Let try this: How is BTU related to Degrees Fahrenheit?

If air is compressed doesn't it get hot? If so, how measure it? But I
guess what caught my eye was when a previous post said that compressing
air does not create heat. But I may be pretty ignorant about the term
HEAT.

Confused Bob

If I remember correcty from chem class 35 years ago:

PV=NRT

pressure * volume = moles * R * Temperature

I don't really remember the units, but I think moles is a measure of
mass, R is a constant (.082?), temperature = degrees kelvin.
Google "ideal gas law" for better info. But solve for T and you get

T=PV/NR

The rest is left as an exercise for the student :-)

Oh no.... not moles !!!

That is almost as helpful to me as Avogadro's Number.

I think I will stick with the brick analogy......................... I
can understand bricks.

I new a Wiley Wilson in Ballard, WA in the early 1980s. Same person?

I remember studying Avogadro's Number. It goes like this: If Jane has
8 avogadros and she makes guacamole from 1/2 of them, what is the
number of avogadros she has left?

Must have been a different guy in Ballard. I didn't get to that part
of the country till about 2002.

T is for temperature. Temperature is not heat. Chemistry is not
thermodynamics.
