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

Why is it fun in the phil. 1.) The new slogan of the Department of Tourism of Philippines “It’s More Fun In The Philippines” has gone viral. This slogan was developed to attract tourists from around the world and has already circulated in social networks such as facebook‚ twitter‚ and tumblr. The said slogan aims to convince tourists why they would rather choose Philippines as their travel destination and why it’s more fun to do things in Philippines. Often times in social networks‚ people’s

“DOT’s “It’s More Fun in the Philippines” tourism campaign lauded.” I do commend the Department of Tourism for coming up with the “It’s More Fun in The Philippines campaign. They are trying to hype up the tourism in the Philippines‚ yes. However‚ In all honesty‚ I don’t see much of the advertisements around. I remember before when the Tourism in the Philippines centered around the phrase “Wow Philippines”. Along Roxas boulevard‚ flew tarpaulins and signs that had that exact phrase. As you got

Education is undoubtedly one of the most important aspects to a child’s development. As a young child‚ I was very lucky to have teachers that I felt I could relate to‚ talk to and who made learning fun. Through my own experiences and through observations of others‚ I came to a conclusion. Sometimes‚ as a parent‚ you may find a teacher who has amazing credentials having graduated from a top university. Some parents automatically think that because the teacher is well educated‚ that he/she is perfect
