Question

When people sleep, their metabolic rate is about 2.6×10−4C/(s⋅kg). How many Calories does a 80 −kg person metabolize while getting a good night's sleep of 8.5 hr ?

Answer 1

7.93 calories

Step-by-step explanation:

To find the total number of calories burned by an 80 kg person during a good night's sleep of 8.5 hours, you can use the formula:

calories burned = metabolic rate * weight * time

In this formula, the metabolic rate is given as 2.6 x 10^-4 calories per second, the weight is given as 80 kg, and the time is given as 8.5 hours. To use this formula, you first need to convert the metabolic rate to calories per hour and the time to seconds. There are 3600 seconds in an hour, so you can multiply the metabolic rate of 2.6 x 10^-4 calories per second by 3600 to get the number of calories per hour. This gives you a metabolic rate of 0.936 calories per hour. You can then multiply this value by the weight of 80 kg and the time of 8.5 hours to get the total number of calories burned. This gives you a total of 7.93 calories burned during a good night's sleep.
