Entropy: Entropy is a measure of the disorder of a system. Entropy comes from the second law of thermodynamics‚ which states that all systems tend to reach a state of equilibrium. The significance of entropy is that when a spontaneous change occurs in a system‚ it will always be found that if the total entropy change for everything involved is calculated‚ a positive value will be obtained. Simply‚ all spontaneous changes in an isolated chemical system occur with an increase in entropy. Like enthalpy

study Today energy is so expensive‚ since the populace on the entire world improves and we consume energy in dozen of forms. Yet all of the energy we use originates in the power of the atom including our sun. The energy we capture for use on earth comes largely from the sun liked solar and other such as geothermal‚ wind turbine‚ biomass_______ . Energy Consumption is a key part of most human activities this consumption involves converting one energy system‚ the conversion of electrical energy to mechanical

Report on High Entropy Alloys(HEA) Introduction: Alloys can be defined as a mixture of two or more elements containing one or more elements containing one metal at the least. From bronze age ‚ alloys have been developed based on one principal element. Later metal matrix composites and inter metallic compounds gained attention. Development in technology and innovation lead to the idea of multicomponent system. These systems consists of multiple principal elements. This was attained by alloying

Respiration: How Cells Harvest Chemical Energy 1. A cell must work just to maintain its complex structure‚ for order is intrinsically unstable. Because of entropy (the second law of thermodynamics)‚ which states that any enclosed system tends toward disorganization‚ cells must constantly use energy to keep themselves in order. If the cell was to stop using energy and let itself go then it would eventually get so disorganized that it wouldn’t function properly. 2. With the help of enzymes‚ the

Entropy When I woke up that Saturday morning‚ I knew something would go wrong. I was planning a trip to San Antonio with my best friend‚ Elizabeth. First‚ my car wouldn’t start. When we finally got the car started‚ we noticed that the air conditioner was not working‚ This is a major problem‚ especially if you live in Texas. We decided to keep going and to just roll the windows down to get some fresh air. Not even ten minutes after doing so‚ it began to rain. This did not slow us down at all. When

THERMAL EQUILIBRIUM AND TEMPERATURE Two systems are said to be in thermal equilibrium with each other‚ if they are at the same temperature. ZEROTH LAW OF THERMODYNAMICS It states that if two systems A and B are in thermal equilibrium with a third system C‚ then A and B must be in thermal equilibrium with each other. Fig. 1.01 shows two systems A and B separated by an adiabatic wall (a wall which does not allow hear flow).The two systems are placed in contact

Title: Study of Solubility Equilibrium Abstract The effect of temperature on the solubility product constant‚ Ksp‚ of potassium hydrogen tartrate in water was investigated in the temperature range of 285K to 318K at normal atmospheric pressure. It was found that the solubility of potassium hydrogen tartrate decreases with a decrease in temperature and consequently a smaller volume of sodium hydroxide is needed to neutralize it. The molar solubility of potassium hydrogen tartrate was calculated
