解析 The First Law of Thermodynamics states that the internal energy U of a system depends on its state, and the increase in internal energy 4U is equal to sum of the heat supplied to the system Q and work done W on the system: i.e. U=Q+W. ...
解析 (i)Internal energy of a system is the sum of the random distribution of kineticand potential energies associated with the molecules of the system(ii)There is no exchange of materials with the environment.(iii)Flow (transfer) of thermal energy (OR thermal energy in transit). ...
The first law of thermodynamics 热力学第一定律 （20）Thermodynamics is a macroscopic science, and at its most fundamental level, is the study of two physical quantities, energy and entropy. Energy may be regarded as the capacity to do work, whilst entropy maybe regarded as a measure of the ...
The movement/motion of energy from one system to another is known as thermodynamics which is explained with the help of several laws of thermodynamics. Thermodynamics is studied at the macroscopic level (dealing with large bodies).Answer and Explanation: The first law of thermodynamics stat...
The first law of thermodynamics states that the change in internal energy of a system equals the net heat transfer into the system minus the net work done by the system. In equation form, the first law of thermodynamics is ΔU = Q − W....
