Question
Chapter 10, Problem 66A
Interpretation Introduction
Interpretation: The water that evaporates through perspiration from the body due to two hours of exercise to be calculated.
Concept introduction: The power to do work or to generate heat is energy. It can be categorize as kinetic energy and potential energy.
Expert Solution & Answer
Answer to Problem 66A
4867.85 g or 4.87L of water would have to evaporate.
Explanation of Solution
Given heat generated by one hour exercise is 5500kJ.
Thus heat generated by two hours exercise is
Given heat of vaporization of water is
Thus 40.6kJ of energy lead to perspiration of 1 mol water.
Therefore, 40.6kJ of energy lead to perspiration of water = 1mol = 18 g water.
1 kJ of energy that lead to perspiration of water is
11000 kJ of energy that lead to perspiration of water is
1000 g of water = 1L of water
Thus, 4867.85 g of water = 4.87L of water
Conclusion
4867.85 g or 4.87L of water is would have to evaporate through perspiration rid 11000 kJ of heat generated during two hours of exercise.
