the evaporator by the compressor To enable the transfer of heat‚ the temperature of the liquid refrigerant must be lower than the temperature of the product being cooled. Once transferred‚ the liquid refrigerant is drawn from the evaporator by the compressor via the suction line. When leaving the evaporator coil the liquid refrigerant is in vapour form. The Compressor The purpose of the compressor is to draw the low-temperature‚ low-pressure vapour from the evaporator via the suction line. Once drawn

The main focus of this experiment was to find the relationship between temperature and the enzyme activity of amylase. This was achieved by attaining amylase enzyme‚ starch solution and potassium iodide (determines if enzymes hydrolyses the starch solution)‚ water bath and a hot plate. The temperatures used for this experiment were room temperature‚ 37oC‚ 60oC‚ 80oC‚ and 90oC. The hypothesis developed was that as the temperature increased‚ so will enzyme activity. Therefore‚ the ability of the enzyme

Does Temperature Affect Enzyme Activity? Introduction As a group‚ we conducted an experiment to see if temperature would affect enzyme activity. We did this because we are studying enzymes and were curious if they would be affected by temperature. We hypothesized that temperature would affect enzyme activity. We believed this because it seemed fitting that something which increased the role or speed of something would be affected by changes in something like temperature. A catalyst is a substance

concentration range (15-30%). P188 in the tested concentrations (15-30%) failed to give the suitable gelation temperature where all the recorded temperature values were till 50oC and the viscosity of P188 solution were too low for nasal administration. Result revealed that formulations containing P188 have found to be higher gelation temperature compared to body temperature. So‚ gelation temperature of P188 in in situ gel was not fulfilling the requirement of in situ gel formulation. The previous findings

The next measurement was after 40 mL of tap water was heated in a beaker‚ and. After a 3 minute observation‚ the temperature reading was 63.0°C. The heated tap water was immediately poured into the calorimeter and its temperature was also observed. The water initially obtained a temperature of 44.5°C and after

mixtures of organic liquids into their original components. Mixtures of two miscible liquids with two different boiling points were separated. Therefore‚ it can be said that the two organic compounds are separated by exploiting the different boiling temperatures of the liquids. Both vaporization and condensation were used in this experiment. The two organic compounds used in this experiment were ethyl benzene and cyclohexane‚ which have the boiling point of 136°C and 80.74°C‚ respectively. This experiment

Thermal Expansion Thermal expansion is the tendency of matter to change in volume in response to a change in temperature‚ through heat transfer. The coefficient of thermal expansion describes how the size of an object changes with a change in temperature. Specifically‚ it measures the fractional change in size per degree change in temperature at a constant pressure. Several types of coefficients have been developed: volumetric‚ area‚ and linear. This is used depending on the particular application

Success of Dugesia tigrina regeneration in different water temperatures Abstract: The experiment at hand aimed to determine if the species Duguesia tigrina has an optimal temperature for regeneration. The experiment used three different spring water treatments of different temperatures. The treatments included a cool 12° treatment‚ a room temperature 25° treatment‚ and a warm 30° treatment. Each of the D. tigrina were cut in half‚ and each half was placed into a designated section of a water treatment

element and the temperature in a refrigerator cooled by the element. The “refrigerator” consisted of a cavity in a block of polystyrene foam with the Peltier element covering the opening of the cavity. A fan on top of it cooled the hot side of the element. The temperature inside the cavity was measured with a thermocouple. The measurements showed that the temperature depends on the current as a second order function and that and that there exist a current for which the temperature reaches a minimum
