1. The problem statement, all variables and given/known data
I have a rather conceptual question, if I can understand it I can probably solve the prblem. Here is the problem: me and my equipment weight is w N. I am climbing a mountain and I climb an elavation of h meters. Now, my body convert 25% of energy burnt from fat into PE. The other 75% appears as heat. Half of the heat generated goes into evaporating sweat. Also given are the following info: fat contains 1000kcal/kg and latent heat of evaporation of sweat is 2.5x10^6 j/Kg 2. Relevant equations mgh wh mL 3. The attempt at a solution ofcourse total work done to go up h meters = w x h J = wh Joules what I do not understand is since 25% of fat burnt is converted into PE, does this mean that this is equal to wh J? or does it mean that 25% of wh is equal to the energy generated by burning fat? Thanks in advance. 1. The problem statement, all variables and given/known data 2. Relevant equations 3. The attempt at a solution 1. The problem statement, all variables and given/known data 2.
