Evaporation

-Film coating involves the deposition of a thin film of polymer surrounding the tablet core It involves the conversion of a viscous liquid into a visco‐ elastic solid as a result of continual solvent evaporation Reasons for coating tablets: ¥ To protect tablet core from environment (e.g. light or moisture) ¥ To mask bitter / unpleasant taste of API in the tablet ¥ To facilitate ingestion of the tablets ¥ To improve appearance of tablets ¥ To improve…

Heat Recovery Steam Generator is a part of a power plant, which generates steam. The heat recovery steam generator used a gas turbine to operate, by using the flue (gas) from the exhaust of the gas turbine Figure 1. The heat exchanges process occurs between the boiler and exhaust gas, which is used to heat water in a boiler to raise the pressure of the steam. [1] In addition, the gas turbine is used for power source due to it has some advantages such as can be started quickly, can be easily…

South Africa is surrounded by three major oceans namely the Atlantic, the Indian and the Southern Ocean. The west and east coast of South Africa are geographically and oceanographically distinct, supporting a wide variety of marine life. The west coast of South Africa is characterised by the relatively cold, slow-moving Benguela Current. The marine life along the west coast is adapted to colder temperatures. The waters of the west coast are nutrient-rich and support a large abundance of fish.…

to real world situations. An example of this is rust. Rust usually occurs when iron reacts with water. By being aware of this, substances can be made to remove unwanted rust. The mass of the collected samples will decrease as it is dried due to evaporation. Excess water that was attached to the samples will disappear into the atmosphere. Possible Balanced Equations: Iron(II): Fe(s) + CuSO4(aq) -----> FeSO4(aq) + Cu(s) Iron(III): 2Fe(s) + 3CuSO4(aq) -----> Fe2(SO4)3 + 3Cu Design…

the well (Source 3). After the fracturing is completed, the internal pressure of the geologic formation causes the injected fracturing, fluids to rise to the surface. Here it may be stored in tanks or pits prior to disposal, where it is open to evaporation and leaking ( Source…

Analyzing Osmosis in Gummy Bears Stephania Turyk and Anastasija Racic March 2016 Pre Lab Questions Why is it so important not to eat or drink anything in the lab? It is important not to eat or drink in the lab because the lab may be full of many contaminations that may enter your food or drink causing you to be very ill. Describe the direction of the flow of water when plant cells are placed in a hypertonic solution. When a plant cell is…

TMI-1 was a pressurized water reactor. It would pull water from the river the plant was stationed on to replace the water that had left the tower due to evaporation at the top of the tower. When the accident happened in the TMI-2 tower TMI-1 just so happened to be offline for refueling. TMI-2 was also a pressurized water reactor like TMI-1, but the amount that it could hold was bigger than that of the first…

an abrupt and catastrophic drought had occurred in Africa causing those in the region to suffer, he reiterates that as carbon dioxide has increased due to the lack of rainfall and increase in drought. This occurs because global warming creates evaporation within large bodies of water while simultaneously sucking moisture out of the soil which increases rapidly with raised temperatures. He further states that the diminishing effect of Lake Chad vastly complicated the problems they already had.…

Have you ever imagined a life without your precious refrigerator? If you don't have a refrigerator, you will have no place to store your fruits and vegetables and will have to do without cold water during summers. Therefore, it is important that you take steps to maintain your refrigerator. One of the common problems you are likely to face when you use this machine is that it runs longer than normal. This will damage the fruits and vegetables you have stored in the fridge. However, this is not a…

The Sumerians developed one of the earliest civilizations on earth from 3500 to 1750BC. Their existence and civilization was not even discovered until the middle of 1800AD. Because the ancient Greeks and Egyptians wrote about the Babylonians most people did not realize that the Sumerians preceded the Babylonians. Furthermore, it was the Sumerians who developed writing, religious and agricultural systems which later the Babylonians continued. During the early 1800's it was the British, German…
