the experiment aimed to determine the specific heat of two different metals‚ Lead and Zinc‚ in order to calculate their individual atomic weight. Theory The calorimeter consists of a metal outer cup‚ a removable metal inner cup‚ which is held in place by a rubber ring‚ and an insulating lid with a small opening for a thermometer. It is a closed system as the air between the inner cup and outer cup insulates the water and heated metal‚ so‚ ideally‚ all heat is contained within the calorimeter (1)

Production Capacity It is highly imperative that management must formulate a strategic plan for operations before any production is carried out. This is basically important in avoiding possible hindrances and excess in capacity. Under capacity may force the firm to cancel production schedules or excess can be fatal due to a broadened fixed cost. Both really would be a financial burden to the firm. Some procedural strategy can be adopted to minimize ill effects of capacity-related problems

Generally speaking‚ there are two methods used in the coal exploitation: over ground and underground exploitation. The choice of different mining methods id determined by the geography conditions‚ coal hierarchy and the sea filling project. Opening mining is often

A variety of procedures are used by psychologists to study the functions of different areas of the brain. Some of them are very old methods and outdated; some of them are most recent in origin and frequently used by modern investigators. The methods help us to study the localization of the functional areas of the brain. One of these methods is the stimulation method. A specific part of the brain may be stimulated either by electric current or by chemicals. Through electrical stimulation‚ we can

I. Methods of research to be used Descriptive research can involve collecting quantitative information‚ or it can describe categories of information such as patterns of interaction when using technology in the classroom. Although it may employ fundamentals of both quantitative and qualitative research‚ descriptive research does not fit neatly into the definition of either quantitative or qualitative research methodology. Descriptive research may be used most effectively within the educational

Separation Techniques If one component of the mixture has magnetic properties‚ you can use a magnet to separate the mixture. Cobalt‚ iron and nickel all have magnetic properties. Note that not all metals are magnetic and magnetism is not a method to separate metals from non-metals. Gold‚ silver and mercury are examples of non-metal substances. Magnetism is however a way to separate magnetic substances from non-magnetic substances is. Magnetism as a separation method is done by taking any magnetic force (Electro

The specific independent variable in Katherine’s investigation would be the amount of sunlight each plant will recieve‚ and the specific dependent variables would be the time of day and the water. 2. Five controlled variables in this investigation would be where she would place the plants‚ the type of plant she will use‚ the type of water she uses for each plant‚ the amount of water she uses per plant and the exact times she waters the plants in a day.

(example: hydrogen) or a gas (example: Hydrogen). Matter can be classified as either a mixture or a pure substance or a mixture. There are two types of mixtures a homogenous mixture and a heterogenous mixture. A homogenous mixture is a mixture that has been thoroughly combined and has been turned into a solution. A heterogenous is a mixture in which the particles has not been thoroughly combined. All mixtures can be separated to get the back to its original form - a pure substance. A pure
