The change of Gibbs free energy (ΔG) in an exergonic reaction (that takes place at constant pressure and temperature) is negative because energy is lost (2). In chemical thermodynamics , an exergonic reaction is a chemical reaction where the change in the free energy is negative (there is a net release of free energy). [ 1 ]
An emergency kit, disaster bag, bug-out bag (BOB), [4] [5] [6] also known as a 72-hour kit, [7] GOOD bag (get out of Dodge), [8] [9] personal emergency relocation kit (PERK), go-bag, survival backpack, or quick run bag (QRB) [10] [11] is a portable kit containing items that would help a person to survive for 72 hours [12] during an escape or ...
Starvation response in animals (including humans) is a set of adaptive biochemical and physiological changes, triggered by lack of food or extreme weight loss, in which the body seeks to conserve energy by reducing metabolic rate and/or non-resting energy expenditure to prolong survival and preserve body fat and lean mass.

A mini survival kit contains essential outdoor survival tools and supplies. It is intended to be carried on one's person at all times, be appropriate to all environments, and be a comprehensive kit without being too large. Mini survival kits are intended to provide the basic needs of a survival situation, self-rescue, assistance or a return to ...
The standard Gibbs free energy of formation of a compound is the change of Gibbs free energy that accompanies the formation of 1 mole of that substance from its component elements, in their standard states (the most stable form of the element at 25 °C and 100 kPa).
In May 1907, Einstein explained that the expression for energy ε of a moving mass point assumes the simplest form when its expression for the state of rest is chosen to be ε 0 = μV 2 (where μ is the mass), which is in agreement with the "principle of the equivalence of mass and energy". In addition, Einstein used the formula μ = E 0 ...
The upper two side-by-side shotgun barrels use special 12.5×70mm ammunition (40 gauge), and the lower single rifled barrel uses 5.45×39mm ammunition developed for the AK-74 assault rifle. The TP-82 has a large lever on the left side of the receiver that opens the action, and a small grip safety under the trigger guard that resembles a ...
Emergency foodstuffs are usually high in caloric content, and sometimes also in nutritional content. Typical emergency foodstuffs are high-calorie foods such as candy bars, nutritional or protein bars, sports or energy bars, hard bread or biscuit (including food ration bars), dried meat (such as jerky), and dried fruit. If water is available ...
