related to heat or temperature, including how heat moves, how materials expand with temperature changes, and the energy stored in heat

(technology) relating to a thermostat, a device that controls temperature automatically

(physics) the release of electrons from atoms or the discharge of energy in the form of radiation or particles

a thermodynamic measure of the degree of disorder or randomness in a system, denoted by S

(physics) the transfer of heat, electricity, or sound through a material without the material itself moving

(physics) the transfer of heat through a liquid or gas by the movement of the fluid itself

(chemistry) the amount of heat required to raise the temperature of a substance by one degree

(cryogenics) the lowest possible temperature, at which atoms and molecules have minimal motion, equal to 0 Kelvin or -273.15°C

an instrument that automatically controls the temperature of a room, machine, etc.

(physics) a source of power that is required to do any work that may exist in potential, kinetic, thermal and other forms

relating to the electric power which is generated by the flow of water

(physics) stored energy that an object has due to its position or condition

a source of power used for lighting, heating, and operating machines

relating to, produced by, or using electricity

the total amount of stored battery energy available to power a device or vehicle until depletion

(physics) an invisible region of force around a charged object that affects other charged objects nearby

a form of electricity generated by friction between two materials, resulting in an imbalance of electric charges on their surfaces

a phenomenon of attracting and repulsing forces that a moving electrical charge produces

to make an object capable of attracting certain metals

either of the two regions at the ends of a magnet where magnetic force is strongest

(physics) magnetism that is created by an electric current flowing through a conductor

(physics) the branch of science that studies how matter and energy behave at the tiniest scales

relating to, producing, or powered by nuclear energy

powerful energy that is produced when the core of an atom is splitted

(physics) a structure that harnesses the energy produced from a nuclear reaction and converts it into electricity

(physics) capable of splitting apart in a nuclear reaction, releasing a large amount of energy

(chemistry) the splitting of a heavy and unstable atomic nucleus into lighter parts

(physics) a nuclear reaction by which the nuclei of atoms combine and form a heavier nucleus, producing nuclear energy

containing or relating to a dangerous form of energy produced by nuclear reactions

energy transmitted through space or matter in the form of waves or particles

the time required for half of a quantity of a substance to undergo a change or decay, typically in the context of radioactive decay or chemical reactions
