and Charles’ Law Vocabulary: absolute zero‚ Boyle’s law‚ Charles’ law‚ Kelvin scale‚ pressure Prior Knowledge Question (Do this BEFORE using the Gizmo.) A small helium tank measures about two feet (60 cm) high. Yet it can fill over 50 balloons! How can such a small tank contain enough helium to fill so many balloons? _The tank is compressing the helium into a denser state but when it is put in the balloons it expands and takes up more space. __________________________________________________________________________

SA: VOL RATIO AND AGAR BLOCKS Conclusion: For this experiment the agar jelly had to be cut in to five different block sizes‚ after that has been done we had to add all five blocks in to the test tube with the acid and time to see how long it would take for the colour to change from a pinky purple to clear. From this experiment I learnt that the bigger the size of the jelly is the more time its going to take for the colour change to take place‚ the colour change represents the rate

Biology Lab Report - Movement in and out of cells (4A) Shiang Chen Ting (24) Sec 313 Introduction The aim of this experiment is to explore the factors which affect the movement of materials in and out of the cells. The dark red or purple colour of Beetroots is caused by a pigment called betalain that is found within the vacuole of the beetroot cells. The pigment remains intact within the cell if the cells are not “stressed” by the external environment. In this exploration‚ two factors that affect

EFFECT OF TEMPERATURE ON CORROSION OF CERMETS ALLOY ABSTRACT Tungsten carbides (WC) are widely used as wear resistant components such as seal‚ valves‚ rings‚ nozzle and bearings. But in some processing operations‚ the environment necessarily includes severe corrosion or extremes of temperatures. In this research‚ commercially cobalt tungsten carbide (WC-6%Co) and nickel tungsten carbide (WC-9%Ni) was examined in seawater (3.5% salinity) to know the effect of temperature on corrosion for both

An investigation into the effects of temperature on enzyme action An enzyme is a biological catalyst that speeds up the rate of reaction in certain biological functions. They play a vital role in many aspects of human physiology and are necessary for the functioning of a number of systems‚ for example in the digestive system to help to break down food. All enzymes have a unique active site that can fit on to a particular molecular arrangement on a target substrate; a substance e.g. carbohydrate

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 little activity would

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

Effect of varying Temperatures on Enzymatic Activity of Bacterial and Fungal Amylase and hydrolysis of Starch Abstract This experiment consisted of setting up a control group of starch in various temperature and then placing both fungal amylases and bacterial amylases in a mixture of starch and placing the solution of amylase and starch in various temperatures of water. After a certain amount of time- different amount of time needs to be used in order to have reliable results- iodine is added
