mitochondria
The mitochondrion is a double membrane-bound organelle found in all eukaryotic organisms, although some cells in some organisms may lack them
work
In physics, a force is said to do work if, when acting there is a displacement of the point of application in the direction of the force
energy transformation
Energy transformation or energy conversion is the process of changing one form of energy to another form of energy
exothermic reaction
An exothermic reaction is a chemical reaction that releases energy by light or heat
nuclear fission
In nuclear physics and nuclear chemistry, nuclear fission is either a nuclear reaction or a radioactive decay process in which the nucleus of an atom splits into smaller parts
thermochemical equation
A Thermochemical Equation is a balanced stoichiometric chemical equation that includes the enthalpy change, ΔH
calorimeter
A calorimeter is an object used for calorimetry, or the process of measuring the heat of chemical reactions or physical changes as well as heat capacity
fusion
In nuclear physics, nuclear fusion is a nuclear reaction in which two or more atomic nuclei come close enough to form one or more different atomic nuclei and subatomic particles
endothermic reaction
The term endothermic process describes a process or reaction in which the system absorbs energy from its surroundings; usually, but not always, in the form of heat
joule
The joule , symbol J, is a derived unit of energy in the International System of Units
melting point
The melting point of a solid is the temperature at which it changes state from solid to liquid at atmospheric pressure
