Plot the graph of lnη vs 1/T

  1. Oct 27, 2014 #1
    1. The problem statement, all variables and given/known data
    Plot the graph of lnη vs 1/T for water (use values from table) and alcohol (values measured previously).
    For water:
    (Temperature in Kelvin)
    T=293.15 η=1.002mPas
    T=308.15 η=0.726mPas
    T=323.15 η=0.548mPas

    For alcohol (measured):
    T=293.15 η=3.202
    T=308.15 η=1.254
    T=323.15 η=0.705

    2. Relevant equations
    lnη=(E/R)*(1/T)-lnC

    3. The attempt at a solution
    I tried just calculating the logarithms of the given values but as expected for values <1 I get negative logarithm values. My question, do I use the negative values as well, or?
