Question

Suppose that a person eats a diet of 2387 Calories per day.Convert this energy into joules.

Express your answer using four significant figures.

Answer 1

To convert the energy from calories to joules, we need to use the conversion factor that 1 calorie is equal to 4.184 joules. Therefore, we can calculate the energy in joules by multiplying the number of calories by this conversion factor.

Given that a person eats a diet of 2387 Calories per day, we can convert this to joules as follows:

2387 Calories * 4.184 joules/calorie = 9975.908 joules

Rounding this value to four significant figures, we get:

Energy in joules = 9976 joules

Therefore, a person consuming a diet of 2387 Calories per day would be obtaining approximately 9976 joules of energy.
