Question

A college student produces about 114 kcal of heat per hour on the average. What is the rate of energy production in joules? answer in:____kJ/h

Answer 1

Given:

Average heat per hour = 114 kcal

Let's find the rate in Joules.

To convert to Joules, we have:

1 cal = 4.18 J

Thus,

1 kcal = 4.18 kJ

Hence, to convert, we have:

114 kcal = 4.18 x 114 = 476.52 kJ/hour

Therefore, the rate in Joules is 476.52 kJ/h

• ANSWER:

476.52 kJ/h
