A 75.0 kg woman habitually eats nasi lemak for breakfast. It is known that a serving of nasi lemak contains 350 Calories (kcal). Concern of her weight, she decided to put an effort to reduce her weight by climbing stairs in her apartment. a) How many joules of energy are equivalent to one serving of nasi lemak? (CO3, PO1, C3) (1 kcal = 4184 Joule) b) How many steps must the woman climb on the stairway to burn all the energy from one serving of nasi lemak that she consumed? Assume the height of a single stair is 15.0 cm. (CO3, PO1, C3) c) The woman learned that human body generally have 25% efficiency of converting energy from food to usable energy. That means for 100 J of energy that she used, only 25 J of them is used to climb the stairs. Based on this fact, how many steps must the woman climb to work off her breakfast? (CO3, PO1, C3)
