A pound of body fat stores an amount of chemical energy equivalent to 3500 Cal. When sleeping, the average adult burns or expends about 0.45 Cal/h for every pound of body weight. How many Calories would a 170 lb person burn during 10 hours of sleep? (Note that 1 Cal = 1 kcal.)
To calculate the number of Calories burned during 10 hours of sleep, you need to multiply the rate at which the body burns calories per pound of weight (0.45 Cal/hour) by the weight of the person (170 lb) and the duration of sleep (10 hours).
Step 1: Find the number of Calories burned per hour for the person's weight.
Multiply the rate of calorie burn (0.45 Cal/hour) by the weight of the person (170 lb).
0.45 Cal/hour * 170 lb = 76.5 Cal/hour.
Step 2: Calculate the total number of Calories burned during 10 hours of sleep.
Multiply the number of Calories burned per hour by the duration of sleep (10 hours).
76.5 Cal/hour * 10 hours = 765 Calories.
Therefore, a 170 lb person would burn approximately 765 Calories during 10 hours of sleep.
