As shown in Fig. 4, the system COP increased first and then decreased with the generating temperature increasing and there existed a maximum value of 0.277 at Tg = 63 °C. The variation tendency of the cooling capacity was similar to that of the system COP, but the maximum value of 734.4 W at Tg = 67 °C. The total pressure of the primary flow in the nozzle was relatively low with the generating temperature set under these conditions. The reason for the
Figure 1 Interpretation of the data Graph 1 indicates that as the dry mass of the water rocket increases, the maximum altitude it can reach when launched decreases. The R2 value, which indicates the strength of the correlation between two variables, where one indicates perfect correlation and zero indicates no correlation, in this graph is 0.989. Moreover, the correlation is negative, which can be seen from the coefficient of the X in the equation (-40.667x+ 30.02). For every gram the rocket’s mass increases the maximum height gets reduced by 0.0407 meters. This specifies that as the dry mass of the water rocket increases, the maximum height it can reach decreases.
The extent of reaction was found to decrease with an increase in temperature from 50 to 60ºC. Because at high temperature, the active site of the enzyme got denatured and no more accessible for distinguish substrate 25. However, with an increase in the enzyme amount above 2 %, decreases the percentage conversion. This can be attributed to disruption of enzyme tertiary structure and denaturation at high temperature
The process of respiration occurs according to Boyle’s law. Boyle’s law states that for a fixed mass of gas at a constant temperature, the volume is inversely proportional to pressure. This means that as volume increases pressure decreases and vice versa. During inhalation the intercostal muscles and diaphragm contract resulting in an increase in the volume of the lungs and hence the thoracic cavity. As the volume increases, pressure decreases creating an area of sub atmospheric pressure within the lungs.
The problem gives four perturbations that the equilibrium is subjected to and gives instructions to explain what should happen in these situations. For Part A, N2O4 gas is added to the vessel (which had been above equilibrium) to total a concentration of .375atm in the reactant gas. This means that there is an increase in concentration on the left side of the equation, so to reach equilibrium the equation needs to shift right. For Part B, the total volume of the vessel is decreased to 0.50 L. Pressure and volume are inversely related (as said in the ideal gas law), meaning that the pressure increases when volume decreases, and when the pressure is high the shift needs to go toward the other side of the equation. In this case, the equation shifts left.
Background Information: Yeast fermentation is directly affected by the change in temperature, because the rate of chemical reactions is affected by temperature. If the yeast has been exposed to its optimum temperature (66.667 degrees Celsius) then it will give off the highest carbon dioxide production. As the temperature gets higher, the yeast will produce more carbon dioxide, until at some point carbon dioxide production will decrease, that is when the yeast cells have become denatured due to the increase in temperature. Chemical reactions
An RER value of 0.85 indicates that the mixture of substrates being metabolised is around 50% fat and 50% CHO. The values for rest and 60W are around this value with 0.81 and 0.87, however when the wattage is increased again the RER values jump up to 0.91 at 120W, and 0.94 at 180W. This suggests that the substrate percentage is now leaning more towards CHO consumption and a RER value of >1.00 indicates 100% energy being produced from CHO under anaerobic
As a result, the number of carbons in a straight chain alkane increases, alkanes become less flammable.  Alkane’s volatility decreases with the increase of the number of carbons in the chain. Volatility refers to the ability of a liquid to change into a vapour state which is the state that substances burn in.  Propane’s Properties . Being odourless and colourless, propane follows the chemical properties of an alkane.
Fig. 6 (a) shows the effect of hydrogen peroxide increase on the MB removal at constant pH 3 and Fe3+ of 40 mg/L. The results show that the degradation rate of MB increases with an increase in initial H2O2 concentration from 100 to 400 mg/L, but in excess of about 400 mg/L; the H2O2 dose of 1000 mg/L, plot of the reaction rate curve is almost horizontal. This could be illustrated that the presence of H2O2 beyond the ratio with Fe3+ does not improve the MB degradation. According to Murry and Parson (2004) hydrogen
That means that there was a small lag phase. As the initial crude oil concentration increased to 20 and 40 ml/L the lag phase raised. In fact, it was found that the lag phase was increased when the initial crude oil concentration was higher due to the slower cell adaptation. This shows that the toxicity of crude oil inhibited MS1 strain at high concentrations (19, 33). Varius types of kinetic substrate consumption and inhibition models have been used to explain the dynamics of microbial growth on different compounds for example Phenol, Toluene, Benzene and p-cresol (16, 32, 34).
2. If the temperature is dropping and the dew point is holding steady, what is your forecast for the relative humidity? Explain your answer. The relative humidity would increase if the temperature dropped and the dew point remained steady. Cooled air is unable to retain much moisture and saturates the air, therefore it increases the relative humidity.
This should play the most major role in your decision making process. A general rule of the thumb is that the higher the amount of cubic centimeters displaced by the engine (cc) the more powerful the product is. The 391 operates at 64.1 cc whereas the 461 operates at 76.5 cc. The cc positively correlates to the engine power output commonly shown as kw. The MS391 has an output of 3.3 kw compared to the MS461 with an output of 4.5 kw.
Respiratory acidosis results from impaired ventilation which produces an increase in PaCO2 levels, leading to increased carbonic acid and H+ ion concentration in the plasma, and lowered pH. If the respiratory acidosis continues, compensation occurs via increased retention of bicarbonate and increased secretion of acid in the kidneys. This is a slow process, taking six to 12 hours for activation and three to four days for full effect. Signs and symptoms of hypercapnia and acidosis are: vasodilation, flushing and warm peripheries; headache and raised intracranial pressure (due to ions, depending on the concentration of vasodilation of coronary blood vessels); drowsiness, confusion and coma; flapping tremor, and muscle weakness. The goal would be to remove the excess CO2 but removing too much could result in the patient becoming
