The second law of thermodynamics states that entropy does not spontaneously decrease. Entropy is a measure of how spread out energy is. As an example, if two systems at different temperatures are in contact, heat will flow from the warmer system to the cooler system until they reach thermal equilibrium (equal temperatures).Khan Academy is a nonprofit organization with the mission of providing a free, world-class education for anyone, anywhere.

One or more free neutrons are also released. If enough fissile nuclei are located close enough together, the neutrons released from one fission can induce further fissions, resulting in a chain reaction. Nuclear weapons utilize fast, uncontrolled chain reactions to produce an explosion. Nuclear reactors utilize slower, controlled chain reactions to generate electricity. The release of energy during fission relates to the difference in total mass of the reactants and products by E=mc^2.Khan Academy is a nonprofit organization with the mission of providing a free, world-class education for anyone, anywhere.

When light nuclei fuse to produce a nucleus lighter than iron, energy is released (exothermic). When heavy nuclei fuse to produce a nucleus heavier than iron, energy is absorbed (endothermic).

Half-life cannot be changed—nuclei cannot be forced to decay faster or slower. Additionally, we cannot predict when an individual nucleus will decay. However, when analyzing a large sample containing many nuclei, half-life allows us to predict how much of the sample will remain after a given amount of time.

Gamma radiation is high-energy electromagnetic radiation (light) which has a shorter wavelength and higher frequency than visible light. Gamma rays are ionizing radiation.

It does this by emitting an alpha particle, a clump of two protons and two neutrons (a He-4 nucleus). The nucleus's atomic number decreases by two, and its mass number decreases by four. The alpha particle is high-energy ionizing radiation—it travels at high speed because it carries away the majority of the energy lost by the nucleus during the decay.Khan Academy is a nonprofit organization with the mission of providing a free, world-class education for anyone, anywhere.

The nuclear radiation emitted during radioactive decay is high energy, ionizing radiation. Nuclear radiation is potentially dangerous to living things but also has many beneficial applications. Types of radioactive decay include alpha, beta, and gamma.Khan Academy is a nonprofit organization with the mission of providing a free, world-class education for anyone, anywhere.
