The first law of thermodynamics is a version of the law of conservation of energy. It states that for a closed system and for any process that begins and ends with equilibrium states, a change in U, the thermodynamic energy or internal energy of a system, is defined by the sum of the ...
aAP Chemistry includes topics, such as the structure of matter, kinetic theory of gases, chemical equilibria, chemical kinetics and the basic concepts of thermodynamics, in considerable depth. The course addresses structure of matter, states of matter, reactions, descriptive chemistry and laboratory wo...
It is the minimum work needed to separate the phases, and energies needed to break adhesive bonds often exceed this by a significant amount, because of work done in deforming the adhesive layer or the adherends. An example where much work is done on stretching the adhesive is a pressure ...

Calculate the work done on the system in Joules when 2.0 moles of N(2) reactes with 6.0 moles H(2), to form NH(3) against a pressure of 1 .0 atm at 27^(@) C.
How do you calculate the change in internal energy in a thermodynamic process? The change in internal energy (ΔU) is equal to the heat added to the system (Q) minus the work done by the system (W). ΔU = Q - W. This is known as the first law of thermodynamics. ...
In other words, the system does work on the surroundings, or positive work is done by the system rather than on the system. If a gas compresses, things are the other way around. In thermodynamics, one adopts a definition of "work" and specifies whether it is positive...
