coagulate‚ the independent was the temperature of the water bath and the control was the deionised water and milk solution. These variables allowed for the experiment to be conducted accurately‚ with unexpected results. This is due to the enzymes being most active at 60ᵒC‚ it was that results were going to be most active at the 41ᵒC which is close to human body temperature. When we compare the enzyme in the low temperatures to the enzymes in the higher temperature we observed that the enzymes were

However‚ the rate of a reaction can be altered either faster or slower depending on certain variables. These variables are concentration‚ temperature‚ surface area‚ and catalysts. A reaction can be made faster or slower with a variation in the concentration of reactants; a reaction goes faster when there is an increase in concentration of a reactant. Temperature allows the reactants to react faster‚ and increasing the amount of energy taken in. Allowing the molecules to react faster. Surface area

INVESTIGATION INTO THE EFFECT OF TEMPERATURE ON CATALASE ACTIVITY AIM The aim of this experiment is to find out the effect of temperature on catalase or hydrogen peroxide. This will enable us to tell at what temperature hydrogen peroxide is most efficient. This (degradation) reaction will help us determine some of the catalase’s different attributes. HYPOTHESIS In this experiment it would be safe to hypothesise that no activity would take place at 1 to 20 degrees. It would be probable that a

Investigate temperature change during a neutralization reaction Introduction: When an alkali neutralizes an acid‚ a salt and water are formed. Aqueous hydrogen ions (H+(aq)) from the acid react with the hydroxide ions (OH-(aq)) from the alkali‚ forming water. For hydrochloric acid and sodium hydroxide: H+(aq) + Cl-(aq) + Na+(aq) + OH-(aq) → Na+(aq) + Cl-(aq) + H2O(l) Hydrochloric acid Hydrochloric acid Sodium Chloride Sodium Chloride Sodium Hydroxide Sodium Hydroxide Neutralization

Introduction: We are conducting this experiment to identify how temperature affects the solubility of salt. To add on‚ by making this experiment we could see how temperature affects the solubility of a substance‚ the maximum number of solute particles that can dissolve in solvent particles. Also‚ how by changing the temperature we could see how if the solubility of the solute would either increase or decrease. This experiment connects with information we learn in class because of how in class

Data Analysis Does temperature affect the strength of Gorilla Glue? If two pieces of wood are glued together at a 90° angle and one is put in the freezer‚one at room temperature‚ and one heated‚ then the glued wood from the freezer will be stronger. The independent variable was the temperature. The dependent variable was the strength of the glue. Some constant variables were the amount of glue‚ the type of glue‚ and the type of wood used. The experimental group was the temperatures. The control group

LAB ACTIVITY: Coastal and Continental Temperature Ranges ANALYSIS: 1) I can tell from the temperature curves that the cities are all in the Northern Hemisphere because it ranges from low to high then back to low again starting in January. 2) The city that has the greatest yearly temperature range is Bismarck‚ N.D. 3) The cause of the greatest range is because the location is located most near the pole. 4) The rates of heating and cooling do not differ much for New York

speed up the activation rates that occur in living organisms. Without enzymes‚ it would be difficult to break down particles like food in the digestion system. Enzymes are all very specific to what chemical reactions they will work with‚ and the temperature‚ pH‚ and salt concentration have to be a specific levels in order for the enzyme to function. The structure of each enzyme has a fixed shape in which a certain the substrate will fit into. The sequence of the amino acids in the enzyme determines
