I am not quite sure of the main reason but here are some: 1. so that the fat absorbed in the small intestine (particularly in the ileum) passes through adipose (fat) tissue first. 2. So that fat by-passes the liver 3.transport of fat in lymph may reduce risk of plaque in arteries
Fossil fuels contain chemical potential energy, which is released as thermal energy when they burn. Nuclear fuel which can undergo fission contains energy by virtue of the change of mass which occurs when the nucleus is split into fragments, initially this is released as kinetic energy which is absorbed in the fuel and released as thermal energy.
Fat stores energy (as described on this linked page). See also:Eating healthy to maintain proper weight
Energy is absorbed from the sun's radiation and causes the water to heat up. If 1 pound of water rises 10F that is 1 BTU
In weight - no important amount at all. 10 minutes is maybe 100 calories. Using the ballpark value of 3500 cals lost equals 1 lb lost. 100 calories would mean about 13 grams, half an ounce. And this is if ALL energy from the ride would come from fat, which it doesn't. A typical value is 1/3 - 1/2 of the energy from fat. Say a quarter ounce.
Elements of Lipids or Fat are: 1. Fat- store energy 2. Steroid- hormone, cholesterol 3. Phospholipids- cell membrane
The liquid to gas phase change will absorb the largest amount of heat energy.
