Boiling Point Elevation Definition - Chemistry Glossary

Boiling point elevation, freezing point depression, vapor pressure lowering, and osmotic pressure are examples of colligative properties. These are properties of matter that are affected by the number of particles in a sample. Boiling Point Elevation Definition Boiling point elevation is the phenomenon that occurs when the boiling point of a liquid (a solvent) is increased when another compound is added, such that the solution has a higher boiling point than the pure solvent. Boiling point elevation occurs whenever a non-volatile solute is added to a pure solvent. While boiling point elevation depends on the number of dissolved particles in a solution, their identity is not a factor. Solvent-solute interactions also do not affect boiling point elevation. An instrument called an ebullioscope is used to accurately measure boiling point and thus detect whether boiling point elevation has occurred and how much the boiling point has changed. Boiling Point Elevation Examples The boiling point of salted water is higher than the boiling point of pure water. Salt is an electrolyte that dissociates into ions in solution, so it has a relatively large affect on boiling point. Note nonelectrolytes, such as sugar, also increase boiling point. However, because a nonelectrolyte does not dissociate to form multiple particles, it has less of an effect, per mass, than a soluble electrolyte. Boiling Point Elevation Equation The formula used to calculate boiling point elevation is a combination of the Clausius-Clapeyron equation and Raoults law. It is assumed the solute is non-volatile. ΔTb  Ã‚  Kb  Ã‚ ·Ã‚  bB where ΔTb  is the boiling point elevationKb  is the ebullioscopic constant, which depends on the solventbB  is the molality of the solution (typically found in a table) Thus, boiling point elevation is directly proportional to the molal concentration of a chemical solution.

Typhoon rise to define piety to Socrates through different definitions ranging from beloved actions to the Justice but neither could satisfy him. Socrates When this written piece is read carefully one can get much knowledge about holiness or It may help to clarify little confusion about the concept of piety and holiness. Socrates argues with Typhoon to get a satisfactory definition of piety or holiness. In response to those arguments my paper concludes that the definitions given by the Typhoon and the arguments posed by Socrates ultimately increase the knowledge of an individual regarding different conditions of piety. His arguments truly clarify many doubts related to the piety. Discussion Argument #1 Typhoon advocates that piety Is persecuting spiritual lawbreaker. Socrates argues that there are various holy actions besides persecuting. My Conclusion One might think that piety is about confronting wrong doers or offenders. But this is not the whole concept of piousness because it is not necessary that something offending must also be felonious for other people. We will write a custom essay sample on Euthyphro or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page It is still not certain that what may lease God or what not and it is only God who knows real intentions behind any action.That is why this definition of Typhoon regarding piety did not satisfy Socrates and he asked for another explanation of piety. Argument # 2 According to Typhoon, piousness Is what Is dear to Gods and rests of the actions are considered to be Impious. On the other hand Socrates argued that It Is never clear that which action is precious to Gods and it becomes more difficult when there My conclusion This argument also enhances the knowledge about piousness because many people believe their own action dear to God while reject others as being controversial.No one can truly define the characteristics of beloved action to Gods. Those who consider certain actions to be a sign of piety must give a though over it. Argument # 3 The next argument that pious is everything loved by God or beloved things of God is pious may seems perplexing but it may also explain confusions about piety. Many of us believe certain particular actions to be pious before God; though this is not the whole truth. Sometimes the smallest actions of a person may lead him to piety. In the same way every apparent pious action may not be a sign of piety for God for he knows the real essence and reason behind it. Further definitions of piety by Typhoon lead to the argument that it Justice may not be piety because it is subjective. A Just action for one may not hold same ground for others. More Arguments Other arguments also declares that it piety is not a result of trading between God and men as God is above everything and it is man who is dependent.
