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?
