Activation Energy Definition in Chemistry Activation energyis the minimum amount ofenergyrequired to initiate areaction. It is the height of the potential energy barrier between the potential energy minima of the reactants and products. Activation energy is denoted by Eaand typically has units of ki...
This alphabetical chemistry dictionary offers definitions and examples of important chemistry and chemical engineering terms. For each term, a brief definition is given, and each link leads to a more comprehensive discussion of the word. From absolute alcohol, which refers to the common name for hig...
Endothermic Process:A process that acquires energy as heat. Molecular Interpretation of Heat and Work: Heat:Stimulates random motion of atoms. Work:Stimulates orderly motion in the surroundings. 2.1.3 Definition of Internal Energy Internal energy = Total kinetic energy + Total potential energy ...
newton moves an object 1 meter. It is named in honor of the English physicist James Prescott Joule. One joule is equivalent to 1 kg m2/s2, which is also called 1 newton–meter. A kilojoule (kJ) is 1000 joules. To standardize its definition, 1 calorie has been set to equal 4.184 ...
This process involves an increase in the entropy of the universe. The objects are at different temperatures, and heat flows from the cooler to the hotter object. This is never observed to occur spontaneously. Again designating the hotter object as the system and invoking the definition of ...
Definition As it is already mentioned, it is the number of independent coordinates. Still, it can also be defined as the number of independent ways by which a system can exchange its energy. As motion is related to energy only, both terms are analogous here. Types of DOF There are 3...
Furthermore, speaking of “absolutely pure substance” cannot be taken for granted, because it is obtained by a sort of induction along different (operational) trajectories and is dependent on the definition of neighbouring substances. The notion of “chemical trajectories” (which has some ...
What's the definition of molecules in chemistry? In chemistry, a molecule is a group of two or more atoms that are chemically bonded together. A molecule can be made up of atoms of the same element (such as oxygen molecules, O2) or different elements (such as water molecules, H2O). Th...
