Thermo example sentences

We take a system containing some quantity of water in a thermos flask or in an insulated beaker.The first law of thermodynamics tells us about the relationship between the heat absorbed and the work performed on or by a system.Note: There is considerable difference between the character of the thermodynamic property energy and that of a mechanical property such as volume.Ozone is thermodynamically unstable and decomposes to molecular oxygen.Laws of thermodynamics apply only when a system is in equilibrium or moves from one equilibrium state to another equilibrium state.The laws of thermodynamics deal with energy changes of macroscopic systems involving a large number of molecules rather than microscopic systems containing a few molecules.With reference to the enthalpy changes associated with chemical bonds, two different terms are used in thermodynamics.The most familiar examples are phase transformation processes, e.g., Ice and water kept in a perfectly insulated thermos flask (no exchange of heat between its contents and the surroundings) at 273K and the atmospheric pressure are in equilibrium state and the system shows interesting characteristic features.In thermodynamics, a different and much simpler concept of the state of a system is introduced.In thermodynamics, a distinction is made between extensive properties and intensive properties.Furthermore, the primary key of owner entity is included as foreign key in such a relation key of owner entity and the partial key of weak entity.We may now formulate another postulate: in an isolated system, there is always a tendency for the systems' energy to become more disordered or chaotic and this could be a criterion for spontaneous change ! At this point, we introduce another thermodynamic function, entropy denoted as S.Thermodynamics deals with energy changes in chemical or physical processes and enables us to study these changes quantitatively and to make useful predictions.The coefficients in a balanced thermochemical equation refer to the number of moles (never molecules) of reactants and products involved in the reaction.The presence of reactants in a thermos flask or any other closed insulated vessel is an example of an isolated system.
