wire‚ the temperature of the wire will be increasing. Measure the temperature using the infrared thermometer. Record the ammeter reading as the temperature increases 10°C before disconnecting the wire from the circuit and measuring the wire resistance immediately using the ohm meter. 4. Repeat procedure 4 when the temperature of the wire increases every 10°C until the highest temperature is reached and the measurements are recorded. Conclusion The hypothesis that when the temperature of a wire

Investigating the effect of pH on the activity of the enzyme catalase. Introduction Hydrogen peroxide (H2O2) is a very pale blue liquid which appears colourless in a dilute solution‚ slightly more viscous than water. It is a weak acid. It has strong oxidizing properties and is therefore a powerful bleaching agent that is mostly used for bleaching paper. Catalase is a common enzyme found in all living organisms. Its functions include the conversion of Hydrogen Peroxide‚ a powerful and potentially

Temperature Effects on Labor Productivity: A Cross-Country Approach Introduction Intro into the topic Hypothesis I will test the hypothesis that higher temperature will adversely affect labor productivity in a country. Outline Purpose The purpose of this paper is to check the effects of temperature on labor productivity to conclude that climate change will have a severe impact on labor productivity in the future. It can be thought of as a domino effect. To begin with‚ populations are increasing

When the baby is born its circulation needs to be changed because now the baby must breathe by own using its lungs. Increased level of pO2 causes spasm of the umbilical arteries and‚ as follows‚ decreased venous return to the right atrium. The vascular resistance in the lungs drops and all cardiac output flows through the pulmonary vessels now. Increased return to the heart through the pulmonary veins causes the raised pressure in the left atrium. As result of the changes described above foramen

going to learn... when is it that we will understand that the well-being of the environment and our survival are intricately woven into each other. Good morning respected teachers and my dear friends ...today I Nikita am going to speak about how human activities are affecting flora and fauna? We are facing a serious crisis in biodiversity‚ the variety of animals‚ plants and their habitats. We humans are part of this biological diversity and depend on it in many ways. The rate that animal and plant

The Beatles were and always have been a huge sensation worldwide. They’ve sold millions upon millions of songs and albums. They have been and forever will go down in history for one of the best bands. The Beatles went on a total of 14 tours around the world. The United States had the honor to host The Beatles tour in 1964 which led to millions of people being struck with Beatlemania. That tour was their 8th one. The Beatles are known for the 4 musicians by the names of Paul McCartney‚ George Harrison

Temperature Rising Global Warming is the increase in the average temperature of the Earth’s near-surface air‚ landmasses‚ and oceans its projected prolongation. Many believe that the Earth is currently facing warming in the ozone layer brought on by the rising levels of trapped gases known as the greenhouse effect resulting especially from pollution. Global warming is‚ in Laymen’s terms‚ altering the balance in energy of the earth (Reid 27). “The topic of climatic change has been in question

Abstract This experiment analyzes the effects of how temperature affects bacterial and fungus amylase and also discovers the optimum temperature for these enzymes. The amylase was mixed with starch at temperatures of 0℃‚ 37℃‚ 57℃‚ and 90℃. Iodine was added to each mixture and colour changes in each case. Bacteria amylase was found to be effective at 55 0C as the temperature dropped drastically from 4.58℃ to 2.33℃. This shows that the amylase catabolized a lot of starch hence little is left which

ELASTIC BAND PRACTICAL Introduction The elastic band‚ or rubber band as it is sometimes known‚ is an item that is generally taken for granted today. Because of their unique elasticity‚ they have many purposes. The main purpose is for storage but they can also be used for crafting. Elastic energy only lasts for a short period of time but is comparatively strong. Aim To investigate the amount that a rubber band is stretched when consistently increasing amounts of weights are placed Hypothesis

What effect does temperature have on the oxygen production of enzymes in an animal’s liver? A temperature which is too high would be able to produce little to no oxygen because of the extreme temperature. Just like a temperature too high‚ a temperature which is too low would also produce little to no oxygen for the same reason. Animals that have livers are considered warm-blooded‚ with very warm temperatures; therefore it would make sense for a warm temperature to produce the most oxygen; but one
