Thermodynamic temperature

Q1) State the normal values for the partial pressure of O2 at sea level (with barometric pressure of 760 mmHg) in the following a. Inspired air b. Alveolar air c. Arterial blood d. Venous blood 1a- 149mmHg 1b-100-104 PaO2(mmHg) 1c-95-100mmHg 1d-40-50 mmHg Q2) Interpret the probable underlying cause when a person becomes unconscious and dies on exposure to an atmospheric pressure of 200 mmHg. When the human body is suddenly exposed to this pressure…

done by Haines on how the atomic structure of FePO4 varies when temperature increases from 294K to 1073 shows few crystal chemical relationships between SiO2 and FePO4. There is a first order variation of cell parameters and atomic orientations with temperatures lower than 980K and α-phase plays a dominant role over β-phase at high temperature. For the α-phase FePO4, the cell parameters increase with a non-linear trend when temperature increases linearly. The volume of the cell expands with…

WRITING EXERCISE PARAGRAPH I FePO4 is a type of -quartz, and when the temperature is relatively low, FePO4 still has the tetrahedral structure as seen in Figure 1. The Fe-O-P bridging angles are more similar between the FePO4 and -quartz. Change in the cell parameters become more significant between temperatures of 294K and 1073K, and it slowly acquires an octahedral structure as the temperature increases. When temperature reaches 980K, the compound transitions and the tilt angles decrease…

Two computation cases were introduced, one with a polyurethane graft and another with a silicon rubber graft. The computations were done under a pulsatile flow. Both cases were computed under maximum peak pressure as mentioned in the method section. The flow volume rate is expressed by integrating on surface as followed: Q=∬_A^ ▒v.dA (5) By integrating flow volume rate in time…

The sun was up to death. It was really hot. I felt as if the only to survive such a day was to sweat a lot. Of course, I was sweating. A lot. My stomach was aching. I have not eaten since that morning. I have spent almost two days just eating some bread with butter. Just a day before like this, I was notified by the U.S. Embassy Brazzaville that I failed my TOEFL test. The Fulbright Fellowship was no longer within my reach. The burden of the pain was still running all over my body. My dream was…

all gases occupy 22.4L in any container under standard temperature and pressure. This information could be valuable in many ways. For example, it proves Avogadro’s Law which states that at a standard temperature and pressure, one mole of any gas will occupy the same value which is 22.4L. Like a puzzle piece, once discovered, it…

a chemical reaction as bubbles indicate a formation of gas, and the formation of gas is a sign of a chemical reaction. Moreover, a new substance was produced, evidence that a chemical reaction occurred. Additionally, in the lab, we recorded the temperature of the water…

In this experiment, the effect of temperature on reaction rate of enzyme will be studied. Peroxidase will be used as test enzyme and the variable to be studied is temperature (°C). At first, the experiment will be carried out at room temperature of 20°C. The temperature of the experimental setup will then be increased by keeping the reactants in a water bath at a temperature of 50°C. The enzyme catalysed reaction rate will also be studied at a lower temperature by placing the reactants in an ice…

For example, when the process is endothermic, the kinetic energy increases since the temperature increases, but remains constant at a phase change. However, during an exothermic process the kinetic energy decreases along with the temperature and during a phase change the energy and temperature will remain constant. The kinetic energy is opposite for each of the curves because as the kinetic energy decreases during the exothermic process…
