Problem 19.23 9 of 16 Constants I Periodic Table In a hot day's race, a bicyclist consumes 7.2 L of water over the span of 3.5 hours. Part A Making the approximation that all of the cyclist's energy goes into evaporating this water as sweat, how much energy in kcal did the rider use during the ride? (Since the efficiency of the rider is only about 20%, most of the energy consumed does go to heat, so our approximation is not far off.) Assume that the heat of vaporization at room temperature is 585 kcal/kg. Express your answer using two significant figures. Hνα ΑΣφ Q = kcal Submit Request Answer
