whether living organisms by respiration convert oxygen into Co2. Introduction: The process by which organisms release energy from food is called respiration. There are two categories of respiration‚ depending on the amount of oxygen available. Aerobic respiration is the most common type of respiration. It requires oxygen- the reason why you are breathing right now. Anaerobic respiration requires no oxygen. The experiment which will take place is the aerobic respiration. Earthworms will be examined

results that have been gathered‚ it tells a variety of different things. Each temperature attempt was done three times to be accurate. First of all‚ the hypothesis (the higher the temperature the faster the reaction will occur) has been proven correct and it proves the theory right. From the results‚ we can see this‚ as the iced water (10 degrees) had the slowest rate of reaction at 1.10 minutes. Then the room temperature water (19 degrees) was tested and had a slightly better rate of reaction at 1

The affect of temperature on the rate of movement of woodlice Aim: The aim of this experiment is to establish whether a change in temperature affects the rate in which woodlouse move. I measured the rate by timing the woodlouse to move a set distance of 20cm‚ and altered the surrounding temperature by submerging a clear tube in water with different temperatures controlled by a water bath. Research: It is to be believed there over 3000 different species of woodlice‚ a total of 42 species

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

Determining the Optimal Temperature and PH of Barley Amylase Abstract The purpose of this experiment was to find the optimal temperature and pH of barley alpha-amylase. I hypothesize that the optimal temperature would be 55 degrees Celsius and the optimal pH would be 5.5. In this experiment‚ the starch is used as a substrate to examine the optimum temperature and pH for the reaction of alpha amylase. It is known that the measuring of disappearance (absorbance) of the substrate starch with iodine

To understand the issue of temperature control of ball mill can better finish grinding. Temperature of ball mill is big issue. Appropriate temperature must be set in production. Temperature not only affects the properties of ball mill material but also the grinding performance of grinding materials. The normal temperature of ball mill is high and there are many reasons
