Because Water's latent heat of fusion is much less than its latent heat of vaporization. In English: It takes less energy to change a gram of ice at 0°C into a gram of water at the same temperature than it takes to change a gram of water at 100°C into a gram of steam at the same temperature.
A gram is about 0.002 pounds.

Gram for gram, lipids release twice as much energy as carbohydrates do.
There are approximatley 4Kcal (calories) of energy per gram of carbohydrates.. This is the same in proteins, but 9Kcal of energy are produced in a gram of fat Hope that answers your question :)
lipids contain much more energy then carbohydrates. One gram of lipids create an average of 423 ATP or 0.47 mol ATP/gram. Glucose, with a molecular weight of 180.16, generates only 36 ATP, or 0.20 mol ATP/gram
One gram of protein provides the body with four calories of energy.
9 kcal/g of energy is contributed by one gram of lecithin in a dietary supplement.
One gram of fat equals 9 calories.
9 kcal/gm
Fusion of 1 g of hydrogen would generate 6.4 × 1018 erg.
1 gram of fat provides 9 kcals......and 1 gram of protein/carbs provide 4 kcals...
The amount of protein (4 kcal/gram), carbohydrate (4 kcal/gram), and fat (9 kcal/gram) that is present.
Fats have the most energy gram for gram. I think that lard (sometimes called shortening) is the highest calorie out of all fats (but it's not much different to all other fats really).
