What is entropy in physical chemistry? Automative anti freeze contains CH_2(OH) CH_2 OH, a non volatile non electrolyte, Calculate the boiling point and freezing point of a 25 mass percentage solution of ethylene glycol in water k_6 water = 0.51^{\circ} Celsius /m k_f water = 1.86^...
Thermodynamics is a branch of science that involves the study of how physical systems work related to temperature and energy. Entropy is a central concept in the laws of thermodynamics.Answer and Explanation: Entropy is a physical property that is associated with the four laws of thermodynamics. ...
Gibbs's free energy is denoted by G and that is used to combine enthalpy and entropy into a single value. Change in free energy is equal to the sum of enthalpy plus the product of temperature and entropy of system.Answer and Explanation: ...
Calculate the change in entropy of half a kilogram of water at 0 degree C when it reaches its point of boiling. Consider that the process is carried out at sea level and that the thermal capacity specific value of water in its liquid phase is c = 4186 J/k 5.50 g of sodium hydroxide...
A thermodynamic system has thermodynamic properties including enthalpy, entropy, and Gibbs free energy. Answer and Explanation: The Gibbs free energy (G) is a thermodynamic property that measures the maximum amount of work that can be carried out by a thermodynamic system under......
