Question

Quizplus · Accepted Answer

Using the given information, we can calculate the amount of energy released from the consumption of 10 liters of oxygen:

Energy released = 4.8 kcal/liter x 10 liters = 48 kcal

We need to convert this to joules (J) since the options are given in joules.

1 kcal = 4.184 kJ
Therefore,
48 kcal = 48 x 4.184 kJ = 200.352 kJ

Rounding off to the nearest whole number, we get:

Energy released = 200 kJ

Thus, option B is the correct answer.
