Abstract The purpose of this experiment was to identify whether density is an extensive or intensive physical property. By using water displacement‚ the volumes of the paper clip samples were measured and the masses were obtained by using an electronic balance. Each mass and volume was unique to their sample so by using their values‚ density was used to identify substances in the lab. After conducting the experiment‚ the results showed that there was a positive slope between the different paper

Exploring Density Simulation Exploration: Login to the PHET Website. A basic property of any homogeneous substance is its density: the ratio of its mass to its volume. The density of a liquid or solid is an intensive property‚ which means that the density does not vary with the size of the sample but only depends upon its composition. The determination of density is a nondestructive physical process for distinguishing one substance from another. The mathematical relationship is: Density= massvolume

The physical environment has determined to some extent‚ the distribution and density of Australia’s population. Discuss. People do not live evenly spread through the world. Australia is one of the counties that considered has a low population density. This is due to approximately 23 million population were distributed unevenly. Besides the physical environment‚ there are also a variety of other factors that have actually worked together to distribute in the Australia’s population that cannot be

1.0 The definition and explanation of ethical principles in the pathology laboratory Ethics is defined by moral philosophy and study of what is right‚ fair‚ just and good: about what should be done‚ not just what is most acceptable or expedient (ref). The four principles of ethics are autonomy‚ non-maleficence‚ beneficence and justice. In this report the ethical principle of non-maleficence‚ where the health care practices and obligations are to do no willful harm‚ execute no negligence or malpractice
