Nicole Reardon Biology 1520‚ Section P2 Effects of penicillin and temperature on the growth of Escherichia coli Abstract Bacteria growth is known to be either augmented or impeded by a number of various factors; in this experiment‚ our group tested how E. coli is affected by penicillin as well as how different temperatures can affect bacteria growth. We know that antibiotics are generally specialized against certain types of bacteria—more specifically‚ some are most effective against Gram-negative

data. As evident in the table‚ the 10oC temperature is very accurate as the range was 0‚ resulting in an error percentage of 0%. However‚ the 35oC temperature had a no clear skew of results as indicated through the range‚ 14 and the error percentage‚ 161.47%‚ suggesting that the trials at this temperature were not very accurate as they were largely inconsistent. The 50oC also proved to have inaccuracies‚ however‚ not as significant as the previous temperature‚

Gas Laws Lab Introduction: The four basic physical properties of a gas sample are pressure‚ volume‚ temperature‚ and number of moles. The volume simply indicates the volume of the container since a gas will take up all space available to it. The temperature indicates the average kinetic energy of the gas particles. For gases‚ the temperature must be converted to the Kelvin unit. The pressure of the gas indicates the number of collisions with each other and the wall of the container. The number

Engineering Workshop 1 Exhaust Gas Treatment Index of contents Introduction Waste gas with harmful traces of gas must be burned in an afterburner. To destroy the harmful traces the temperature after the burner must achieve 900°C. The preheater can`t resist a temperature of 700°C. Therefore quench water in a mixer will be used to protect the heat exchanger. The waste gas has the following properties: Waste gas composition: Mole fraction(= 0‚9890

ways to increase the reaction rate: increase temperature‚ add a catalyst‚ increase surface area‚ and increase the concentration of reactants. The objective of this lab was to experimentally show how temperature and surface area impact the rate of reaction‚ so only two of these methods were tested. The evidence indicates that increasing surface area increases the reaction rate‚ and increasing temperature also increases the reaction rate. Temperature is the measure of the average kinetic energy of

Greenhouse gas emission What is greenhouse gas? A greenhouse gas is a gas in an atmosphere that absorbs and emits radiation within the thermal infrared range. Many greenhouse gases occur naturally‚ such as water vapor‚ carbon dioxide‚ methane‚ nitrous oxide‚ and ozone. Others such ashydrofluorocarbons (HFCs)‚perfluorocarbons (PFCs)‚ andsulfur hexafluoride (SF6) result only from human industrial processes. Greenhouse gases act like a blanket around Earth‚ trapping energy in the atmosphere and causing
