Fawzi Abdelgani Ahmad . Experiment 1: Experimental Uncertainty (Error) and Data Analysis Jan/30/2013 PRELAB: 1. Do experimental measurements give the rule value of a physical quantity? Explain. No. Statistical methods are used to establish the deviations in the measurement. 2. Distinguish between random (statistical) error and systematic error‚ and give an example of each. Random errors are caused by unknown and unpredictable changes in the experiment like mechanical

To determine the heating and cooling curve of water Design: What we are going to do is investigate the phase changes and what the heating curve of water is. We are going to do this is by heating up 100ml of water on a Bunsen burner then adding ice cubes. Use a thermometer to measure the temperature every 30 seconds until it reaches a plateau. Hypothesis: As more time passes‚ the temperature of the water increases. Independent variable: Time Dependent variable: Changing water temperature

6. Applications * Is it possible to add heat to a body without changing its temperature? Yes. It is possible to add energy to a body (in the form of heat) and not raise its temperature by causing a phase change. When you heat ice it takes energy to convert it from ice to water‚ but does not change the temperature of the body until it is all converted. The principle behind this is what we call latent heat. It refers to the energy (or heat) required to change the state of a substance without changing

Banana (Musa Paradisiaca) Peel Shoe Polish | Abstract:Shoe polish is used to shine‚ to maintain the appearance and to sustain the quality of the shoes. Based on the information in the written articles‚ banana peels can be used to shine shoes so the researcher decided to come up with the study of making a shoe polish out of banana peelings. The study aimed to produce a cheaper but better alternative shoe polish.The researchers used banana peels‚ kerosene and candles in making the product. In making

The Jewish Scripture starts right at the beginning of time itself‚ where God created the universe‚ and only then did he create the earth (Genesis 1). Right from the beginning God has had an intimate connection between God and the world‚ and this connection is believed to continue throughout time. From the moment god created humanity (Gen. 1:26)‚ we were created for the one purpose to protect the earth. But it is in the story of Noah that we perhaps truly learn about the role that God had created

TUBERCULOSIS Tuberculosis‚ commonly known as TB‚ is a contagious and an often severe airborne disease caused by a bacterial infection. TB typically affects the lungs‚ but it also may affect any other organ of the body. It is usually treated with a regimen of drugs taken for 6 months to 2 years‚ depending on the type of infection Tuberculosis was popularly known as consumption for a long time. Scientists know it as an infection caused by M. tuberculosis. In 1882‚ the microbiologist Robert Koch discovered
