The ideal gas law, also called the general gas equation, is the equation of state of a hypothetical ideal gas. It is a good approximation of the behavior of ...

In thermodynamics, enthalpy /ˈɛnθəlpi/, is the sum of a thermodynamic system's internal energy and the product of its pressure and volume.

The ideal gas law states that PV = NkT, where P is the absolute pressure of a gas, V is the volume it occupies, N is the number of atoms and molecules in the ...

2023/7/7 -Comparing the previous two equations shows that at constant pressure, the change in the enthalpy of a system is equal to the heat flow: ΔH=qp.

The (E + p * V) can be replaced by the enthalpy H. H2 - H1 = Q. From our definition of the heat transfer, we can represent Q by some heat capacity coefficient ...

2017/2/12 -The partial of V with respect to U at constant P is the reciprocal of the partial of U with respect to V at constant P. Share.

At the same temperature and pressure equal volumes of all gasses contain the same number of molecules. V = n (a constant). V = n (RT/P). Guy Lussac found that 1 ...

2023/11/24 -Ideal gas, or perfect gas, is the theoretical substance that helps establish the relationship of four gas variables, pressure (P), volume (V), ...

If x is a chance variable we will write H(x) for its entropy; thus x is not an argument of a function but a label for a number, to differentiate it from H(y)say ...
