So you are adding energy to your carrots because the fridge removed too much energy, all so you can eat a low-energy snack.
- perilunar 8y agoDoing the numbers: according to Wikipedia[1], carrots contain 173 kJ (41 kcal) of food energy per 100g, and are 88% water. To freeze 100g of carrots requires 100g x ~80cal/g (the enthalpy of fusion of water) = 8 kcal. i.e. 16 kcal to freeze and thaw again. Given the inefficiencies of the fridge and your heating method, you are probably wasting more energy than is actually in the carrots. 1. https://en.wikipedia.org/wiki/Carrot https://en.wikipedia.org/wiki/Carrot
