her physical well-being. Osteoporosis is condition that affects the bones to become weak‚ fragile and possibly become fractured. If an individual has got brittle bones‚ they encourage fractures and limit mobility if he/she is diagnosed with the disease. In osteoporosis‚ the bone mineral density is reduced‚ bone will deteriorate‚ and the amount and variety of proteins in bones are altered. In a DEXA scan‚ the bone mineral density measurement is calculated using standard deviation called T score. If

You must also have your watch or a timer (you will record time in one of the experiments). 1.1 MEASUREMENT OF THE DENSITY OF A LIQUID 1.1.1 Objective The density of a liquid is to be measured using a hydrometer. 1.1.2 Theory A hydrometer uses the principle of buoyancy to determine the specific gravity of a liquid. Here‚ the weight of the hydrometer (set by the metal spheres in its

(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?

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
