Amount Heated 44

  1. Jan 21, 2007 #1
    1. The problem statement, all variables and given/known data
    A)If an athlete (whose mass is 60.0kg) has an energy conversion effiency of 24% and she has an average power of 325W when climbing stairs how high would she be able to climb with the energy consumed from eating 4 potatop chips(28g of chips has 610 kJ of energy and 28g of chips is approximately 15 chips.
    B)If the bag of chips in the above questions had been burned and used to heat water from 13degrees celcius to 20 degress celcius, then how much water was being heated(assuming 100%energy conversion)

    2. Relevant equations
    Eout/Ein*100%


    3. The attempt at a solution

    m=60.0kg
    Efficiecny=24%
    P=325 W
