The Rate of Diffusion in Different Temperatures Purpose: To see if the temperature of a solution will change the rate blue diffuses in it. This will be tested by timing how long it takes dye to diffuse in warm water‚ cold water‚ and room temperature water. Hypothesis: I think that the dye will diffuse at a faster rate in the warm water than in the cold water. I believe that the room temperature water will have the dye diffuse faster than the cold water but slower than the warm water. Variable:

this Lab What is the goal of this lab? What question is it trying to answer‚ or what problem is it trying to explain? The goal for this lab is to be able to get the boiling water’s temperature to increase by adding table salt. The problem it is trying to explain is‚ how does table salt affect the boiling temperature of water? does it increase or decrease? or does it stay the same? Hypothesis After reading the lab instructions - but before starting the lab - record your best “educated guess”

The effect of temperature on a reaction rate In this experiment I shall be investigating how temperature affects the rate of reaction Rates of reaction The Factors that affect the rate of reaction are temperature‚ surface area‚ concentration‚ catalysts‚ light and pressure Surface area – Surface area is the amount of solid surface that is available for reaction - Only affects solids so this will not affect our

After 14 years of trial and error‚ he developed a process he called Appertizing. Fruits‚ vegetables‚ fish‚ or meat was sealed in stoppered bottles and the filled bottles were immersed in boiling water; the heat sterilized the bottles and food alike. Appert knew nothing of enzymes or bacteria‚ nor did anyone else in his day. He did observe that when food was heated in the sealed bottles‚ the food remained good as long as the seal was not broken. The food remained edible until the bottles were

experiment to find the optimum temperature and pH for starch on amylase. The experiment was carried out in one day. The researcher and a partner did the experiment based on a lab manuel from class. Data was collected from the experiment and to be displayed on graphs. Then the optimum pH and temperatures were to be calculated based on the findings. The hypothesis was disproved due to the optimum pH of 5 but the other findings supported the hypothesis of the optimal temperature being 45 degrees Celsius

Research Report Leisure activities Abstract Leisure activities play a significant role in daily life of overseas students who have heavy burden of study. The purpose of this study was dissect the attitude of international students for leisure activities and examined the reason why they changed their leisure activities after coming to Australia. A questionnaire was designed collectively and distributed to fifty students from the UWS College. The findings indicated that majority of international
