Question

An ice cream has a marked value of 700 kcal. How many kilowatt- hour of energy will it deliver to the body as it is digested

Moderate

Solution

$1 kcal = 10^{3} Calorie = 4200 J = \frac{4200}{3 .6 \times 10^{6}} KWh$
$∴ 700 kcal = \frac{700 \times 4200}{3 .6 \times 10^{6}} kWh = 0 .81 kWh$
