Write 7 pages thesis on the topic isentropic expansion of ideal gas. By recording and using relevant pressure measurements with the help of suitable pressure gauges. The value of the specific heat capacity of air could be calculated. A relatively low percentage error in the readings and average value very close to the expected value (precision value) led to the conclusion that the experiment and the simulated adiabatic expansions were quite precise and reliable.

The specific heat (C) is critical because it determines how quickly a substance will heat up or cool down. It is a quantity of heat that is required to change the temperature of 1 kilogram of a substance by 1 degree Celsius. Specific heat capacity is a quantity central to the thermodynamic analysis of a substance.

In this experiment, the pressure was the best parameter to monitor and evaluate, and thus an equation relating the specific heat and the two pressure readings had to be derived. The derivation required the application of the first law of thermodynamics to the adiabatic expansion process and using the ideal gas law, making an assumption that the air behaves like an ideal gas.

In thermodynamics, an isentropic process is a process that takes place from initiation to completion without an increment or decrement in the entropy of the system. In other words, the entropy of the system remains constant. Entropy is a form of energy.

If a process is both reversible and adiabatic, then it is an isentropic process. An isentropic process is an idealization of an actual process and serves as a limiting case for an actual process. For an adiabatic process, there is no transfer of heat energy.

Before the experiment, the atmospheric pressure, P2 was measured using the barometer so as to determine the absolute pressures of the cylinder. In a similar way, the room temperature T1 was measured using the mercury in a glass thermometer.

The vessel was gradually pressurized to 5psig and the air supply turned off followed by the closing of the valve in order to isolate the compressed air inside the tank.&nbsp.

Write a 5 pages paper on light and darkness of the renaissance period. The works of antique art were used extensively to preserve the uniqueness of the ancient artistic identity and, simultaneously, reconsider the most vital elements of creative art. However, the idea of uniting space gradually transformed into a unique paradox, which ultimately put an end to the era of Renaissance: according to Panofsky, “The Middle Ages had left antiquity unburied and alternately galvanized and exercised its corpse. The Renaissance stood weeping at its grave and tried to resurrect its soul” (in Ermarth 27). Simply stated, instead of preserving the uniqueness of antiquity, Renaissance gradually shifted toward distorting the ideas of the past. Consequentially, anachronism became the dominant trend of substitution, which replaced the authentic past with massive cultural misperceptions and, ultimately, resulted in a colossal failure of the Renaissance to produce a permanent change.

Since the earliest years of the cultural Renaissance, the idea to erase the boundaries of temporality and develop a new awareness of time and space had been one of the dominant trends. That the Renaissance was the first cultural era to choose a past for itself is difficult to deny (Heller 90). Really, the idea of the Renaissance initially rested on a belief in the unity of space and rationalization of time, which aimed at redefining the most important historical events through the prism of the new human consciousness (Ermarth 25). To a large extent, a redefinition of time and space during the Renaissance owed a lot to humanism (Ermarth 25). Renaissance had to reduce and deny the discontinuities in the medieval beliefs about history. Further, the Renaissance had to build new human awareness about time, the distinctions in which would rely on the contrast between eternity and time, and not a contrast between present and past (Ermarth 25). The elimination of the persistent distinction between past and present during the Renaissance implied that historians and creative geniuses during the Renaissance considered past and present equally informative (Ermarth 25). Such attitudes toward temporality and space matched the moral purpose of the Renaissance because they helped to represent and preserve the most significant elements of historical achievement (Ermarth 25).
