The typical western diet is energy dense: a lot of kilocalories compressed in a small volume or weight. most people know that eating low-density food is the best way to control the caloric intake and maintain weight. Dark, leafy greens are great as they contain a lot of essential nutrients like vitamins and fibres, and very less amount of fats and carbohydrates. Potatoes on the other hand are full of starch, which gets stored as fat in the body after its break down into simple sugars. If someone wants to consume a potato, then they should eat after boiling and blanching it, and not by frying it in oil. Fried food tends to have more calories than the boiled counterpart.

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
