Purpose: To find out the densities and to find out the name of the unknown metals. (Based on the extensive and intensive properties) Check up the words mass‚ volume‚ density‚ extensive properties‚ and intensive properties. Where do the units for mass and volume) come from and what do they mean? What is the density of distilled water? What is Archimedes principle? Does temperature affect the density of a solid? Liquid? Gas? Materials: Safety glasses‚ 10‚ 25 or 50 mL graduated cylinders

was to familiarize ourselves with different techniques used in the lab‚ taking proper measurements‚ and how to use the International System of Units (SI). Throughout lab we learned about mas‚ volume‚ length and temperature‚ and to be able determine density and concentration. To be able to documents properly and make effective observations we must be able to understand the International Measurement System. Length‚ temperature‚ time‚ and volume are measured by this system. There are many different

thermometer are adjusted to specific densities by the differing amounts of liquid and even the type of liquid within the glass. The different densities will be affected by the waters density‚ which changes as it expands or contracts with temperature difference. As the temperature within the room heats up‚ so does the temperature of the water within the vertical glass tube. Once the water within the thermometer is room temperature‚ the glass bubbles densities will either be more or less dense than

Solutions (Week-01) Chapter-01 1-12 A plastic tank is filled with water. The weight of the combined system is to be determined. Assumptions The density of water is constant throughout. Properties The density of water is given to be = 1000 kg/m3. Analysis The mass of the water in the tank and the total mass are mw =V =(1000 kg/m3)(0.2 m3) = 200 kg mtotal = mw + mtank = 200 + 3 = 203 kg Thus‚ 1-14 The variation of gravitational acceleration above the sea level is given as

Introduction Hydrostatic weighing is an indirect measurement used to predict body fat percentage. It is typically the most accurate means of determining body fact percentage‚ and is based on measuring an individual’s body density. Archimedes’ principle explains that the upward buoyant force exerted on a body immersed in a fluid is equal to the weight of the fluid that the body displaces. Due to the fact that body fat is less dense than water‚ it increases one’s buoyancy‚ while the fat-free mass

The film happens with a great taste of honesty. It teaches lessons you can use in your daily lives. The movie starts with the Gardner couple having problems‚ which is a common scene for people nowadays. The protagonist earns money by selling bone density scanners which he sells to medical institutions‚ which does not sell much. Chris Gardner’s lack of ability to make a living made her wife Linda to leave them. It gives us the picture that people can be full of other’s crap that they will leave you
