Confused ?

Temperatures:

F-32 = 1.8C
F= 1.8C + 32         (eqn 1)

Differentiating,
1 delF = 1.8 delC          

But

180 change in F = 100 change in C = Temp diff between vap. temp and freez. temp.

  1. ???
    1 delf = 1.8 delC nahi buddhu
    del F / del C = 1.8

    so 100 change in C = 180 change in F

    r u seriously doing a phd?

  2. del F / del C =1.8 (eqn 2)

    or,

    del F = 1.8 del C (eqn 3)

    or,

    1 del F = 1.8 del C (eqn 4)

    I fail to see your point.

  3. Ha Ha.. too much

    Okays, let me explain

    Here del F and Del C are variables like x and y. so x = 1.8*y. Hence when y moves by 100, x moves by 180.

    y is del C and x is del f so, 180 change in F = 100 change in C

    You are not treating delF and delC as variables when you say 1delF = 1.8 delC..
