essence of most of Stoppard’s plays‚ in that they seek to find out the hidden order behind chaos. Stoppard‚ as an artist‚ tries to understand and convey the real identity of the human being. He accompanies this very theme with the conceptions such as entropy and the second law of thermodynamics‚ history‚ love and irreversibility of time in two historical periods. Stoppard makes use of the internal paradox of this theory as a rich metaphor‚ and as a trajectory for his characters to gain knowledge. The

law we can see some energy always escapes into the outside world‚ thus leading to inefficiency. This escape can be explained using The Second Law of Thermodynamics. The Second Law of Thermodynamics is otherwise known as the Law of Increased Entropy. ‘Entropy’ is defined as quantity of unusable energy within a closed or isolated system. According to this law‚ the quality of matter or energy depreciates slowly over time. Usable energy is used for some form of output‚ growth and repair. In all these

is determined from free energy‚ or Gibbs free energy. The equation (1) gives the relationship of how entropy (∆S) and enthalpy (∆H) along with temperature affects the amount of free energy‚ and henceforth the spontaneity. A spontaneous process may be quick or slow‚ and it is only affected by temperature and energy‚ therefore it is not related to kinetics or reaction rate. equation (1): If entropy is less than enthalpy‚ the enthalpy term determines if the reaction

Tartrate Wang Haina 1. Aim 1. To determine the solubility of potassium hydrogen tartrate (KHT) at various temperatures from 10°C to 50 °C‚ and determine the corresponding Ksp at these temperatures. 2. To obtain the changes in enthalpy and entropy of the dissolution of KHT from the dependence of Ksp on temperature. 2. Results and discussion 2.1 Collection of data A portion of KHT (1 to 1.5 g) was added into about 100 mL of deionised water to prepare a saturated KHT solution. Several such

AIM: The aim of the experiment was to determine the enthalpy (ΔH)‚ entropy (ΔS) and Gibbs free energy (ΔG) for the Rhodamine β-Lactone Equilibrium. To accomplish this‚ a manual spectrophotometer was used to determine the maximum absorbance of a sample of Rhodamine β-Lactone. The absorbance of the sample was then measured over a range of temperatures from which the equilibrium constant (K)‚ enthalpy (ΔH)‚ entropy (ΔS) and Gibbs free energy were then calculated.
