1g of fat contains 9 calories.
1g of carbohydrates contains 4 calories.
1g of protein contains 4 calories.
1g of alcohol contains 7 calories.
Less than 1% of the Sun's energy is absorbed by Earth's geosphere. The majority of the Sun's energy is absorbed by the atmosphere and surface of the Earth.
The value of the Rydberg constant is approximately 109,677 cm-1. It relates to the energy levels of hydrogen atoms by determining the wavelengths of light emitted or absorbed when electrons move between different energy levels in the atom.

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.
The acid value of fat is a measure of the amount of free fatty acids present in the fat. It indicates the degree of hydrolysis or rancidity of the fat. The acid value is typically expressed as the amount of potassium hydroxide (KOH) in milligrams required to neutralize the free fatty acids in 1 gram of fat.
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.
Fat stores energy (as described on this linked page). See also:Eating healthy to maintain proper weight
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
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
Elements of Lipids or Fat are: 1. Fat- store energy 2. Steroid- hormone, cholesterol 3. Phospholipids- cell membrane
1 gram of fat yields the greatest amount of energy when metabolized, providing 9 calories, compared to 4 calories from 1 gram of carbohydrates or protein.
1 gram of fat provides 9 kcals......and 1 gram of protein/carbs provide 4 kcals...
