Is Activation Energy Positive Or Negative? The activation energy for an elementary chemical reaction is always positive and no one will change that. It is different with the apparent activation energy, but it has nothing to do with the former. Why is activation energy positive? To get started, all chemical reactions require activation energy, even
Is Internal And Heat Energy Same? Internal energy is a measure of the amount of kinetic and potential energy possessed by particles in a body and is measured in Joules. Heat energy on the other hand only concerns transfer of internal energy from a hotter body to a colder body. What is the formula of
What Are Thermodynamic Properties? Thermodynamic properties are defined as characteristic features of a system, capable of specifying the system’s state. … If the units were changed from per mass to, for example, per mole, the property would remain as it was (i.e., intensive or extensive). What is thermodynamics property and its classification? Classification of Properties
What Are The Two Forms Of Internal Energy? The internal energy of a system is identified with the random, disordered motion of molecules; the total (internal) energy in a system includes potential and kinetic energy. What are the types of internal energy? Sometimes it is convenient to represent the internal energy as a sum of
What Is Internal Energy And What Are Its Components? Internal energy U of a system or a body with well defined boundaries is the total of the kinetic energy due to the motion of molecules and the potential energy associated with the vibrational motion and electric energy of atoms within molecules. Internal energy also includes
What Is The Change In Internal Energy Of The System When No Heat Is Absorbed By The System From The Surroundings But Work Is Done By The System What Type Of Wall Does The System Have? When no heat is absorbed by the system them from the surroundings, but work (w) is done on the
Which Term Is Defined As The Rate At Which Work Is Done? Scientists define power as the rate at which work is done, or the rate at which energy is expended. In words: Power is the amount of work done divided by the time it takes to do that work. Which term is the rate
