...? Population density and its effects on the socioeconomic characteristics of a community Literature review 1 Co-relation between Human Populationand development The well-established link between population and community development (urban and rural) has long been subjected to different kinds of interpretations by different authors. As per the Malthusian theory, the population growth of any country or community can lead to scarcity of resources and a subsequent economic degradation and a decline in wealth causing widespread poverty (Malthus, 1807). However, the contenders to this theory opine that population growth is a condition that can be used favourably by educated classes to create new technologies and increase the production... which...

...?SEPARATION OF MIXTURES PURPOSE This experiment was performed to become familiar with the separation of mixtures containing solid components. DATA Table 1. Recorded Weights During the Experiment Before Separation A. Weight of weighing dish 0.6 g B. Weight of mixture + dish 4.7 g C. Net weight of mixture (B - A) 4.1 g During Separation D. Iron fillings 1.2 g E. dry sand 0.4 g F. Benzoic acid 0.2 g G. Salt 0.7 g H. Total weight of separated solids (D+E+F+G) 2.5 g Comparing before and after separation Percent loss during procedure ([4.1-2.5/4.1]*100) 39% OBSERVATIONS Table 1 summarizes the weights recorded during the experiment. As can be seen, the total weight of the mixture’s components after separation...

...? Low Density Polyethylene Introduction Low-density polyethylene (LDPE) was first invented by Imperial Chemical Industries (ICI), UK in 1933.Since then technology has been improved to have currently two basic processes–tubular and autoclave for manufacturing of LDPE. ICI had employed the process of autoclave when they first commercialized the process in 1938. The tubular process was first invented by BASF in 1938 though it took another 15 years to commercialize the production processes. Cost reduction and product enhancement has been the goal of each manufacturer over the years. In recent years, another dimension of environmental aspect has been added to reduce the global warming and related factors....

...to evaluate density of an irregular solid; According to Willis and Shirley (1999), different bodies float differently in fluids of different densities depending on the up thrust force. However, if the density of the given body is higher than that of the relative fluid, the body completely sinks. Normally, water is used in many experiments since it is a universal fluid and has a standard density of unity. Moreover, it is easily available. Density of any given solid is given by; mass of the given solid divided by the volume. For regular bodies, the volume can be easily evaluated using...

...? Population Density POPULATION DENSITY Population density is a measure that calculates the concentration of human in a particular area. When there is a lot of population in one place there are quite a lot of problems in the place, people fight for food and every other resources. There is a lot of competition as the resources are always in limited quantity in areas with dense populations. An area with dense but homogenous population has quite a better situation. The people all belong to the same kind and therefore, they learn to maintain status quo among them. They choose a leader unanimously and look for guidance towards that group that they have chosen. The limited resources are not...

...commonly known as 1.00 g/cm3 or 1.00 g/ml is found empirically to be 0.998 g/ml whereas the density of copper which in theory is approximately 8.94 g/ml turns out 8.5 g/ml in the lab.
The apparent slight differences between the actual and theoretical figures may be accounted for by error through inaccurate reading of measurements with the device or tool used. Another source of error (other than human fault) may be attributed to unnoticed defect in apparatus or measuring scale which has not been properly calibrated. Density of solid or liquid materials is an intensive property of matter that is why it does not depend on the quantity of material in reference to being mass per unit volume....

.... The experimental density for the pennies is 7.54 g/mL. This identifies a five percent experimental error relative to the literature value of 7.18 g/Ml. The error can be attributed to inaccurate readings. The identified relationship between mass and volume to define density means that the Archimedes method can be used to determine densities of other substances, including liquids that are insoluble in water. The experiments therefore recommend the approach for estimating density of substances.

...Lab Report Table of Contents Objective Experimental Data Data Analysis Results Discussion and Conclusion Works Cited Objective This experiment consists of two parts, the first part being computing for the volumes of several objects from measurements of its dimensions empirically as well as investigating error propagation; and the second part being the derivation of the density of objects again from empirical measurements and in the context of error propagation (Cornell).
