The Effect of Osmosis on Potato Tissue When Placed In Different Essay

The Effect of Osmosis on Potato Tissue When Placed In Different Concentrations of Sugar Solutions - Essay Example This is in contrast to the potato slice in the first beaker in which only 1 teaspoon of sugar was dissolved and which has shrunk the least. This pilot experiment will now be conducted in a much more accurate fashion and the investigation will deal with sugar in moles per litre of solution and the weight difference of the potato slices will be determined in order to correlate the sugar solution molarity with the change in weight of the potato slice. Hypothesis- Place potato tissues of the same dimensions and weight and taken from the same potato in sugar solutions of different molarities (a measure of concentration i.e. the number of moles of sugar present in 1 liter of solution), all at the same temperature and pressure, then osmosis takes place and there will be a difference in the weights of potato slices in the different samples. Materials needed to conduct the experiment- a sharp knife, a weighing balance, 4 beakers, 4 potato slices, sugar solutions of different concentrations of sugar-0.1M, 0.2M, 0.3M and water with no sugar dissolved in it. (around 68F/20C) and pressure.

LOGISTICS & OPERATIONS MANAGEMENT 3 Essay Example | Topics and Well Written Essays - 500 words

LOGISTICS & OPERATIONS MANAGEMENT 3 - Essay Example Thus managers can consider the inventory management problem to be a part of operations scheduling problem. Conventionally managers take a narrower view of the delivery. The timing of activities may have a direct impact on resources and the level of service (Naylor, 2002). The purpose of capacity management is the planning task, and the modification of capacity is the key problem area in system control. Capacity decisions will have a direct impact on system performance and on both resource utilization and customer service. It is important to note that organizations cannot operate without good capacity management. For instance, excess capacity gives rise to low resource productivity, while inadequate capacity means poor customer service. Decisions made in other areas have a direct impact the other area. Inventory management is aimed to plan and facilitate the provision of effective customer service. For instance, organizations cannot exist without stocks of raw materials, work in progress or, where appropriate, output goods. The planning of inventory levels, the control of inventories and the maintenance of such stocks are crucial for production and successful performance.
