Homework Help: Temperature Change

  1. Apr 6, 2010 #1
    1. The problem statement, all variables and given/known data
    One day you notice that the outside temperature increased by 29° F between your early morning jog and your lunch at noon. What is the corresponding change in temperature in each of the following scales?


    2. Relevant equations

    Tc = (5/9)(Tf - 32)
    T (kelvin) = Tc + 273.15

    3. The attempt at a solution

    Ti + 29F = Tf
    Tf-Ti = 29F

    Tc = (5/9)(29-32) = -1.66667C

    I am confused to why this answer is incorrect.

    If you are only interested in a change of temperature you don't care about the zero points of the scales, you just need to know how many F is a C - and so how many C in 29F
