Biology Tuition Singapore Secondary Science Tuition – Digestion – FOOD-BORNE DISEASES   When food or drinks are contaminated, food-borne diseases will occur. Food-borne diseases are also known as food poisoning. Food-borne diseases are caused by the presence of harmful bacteria in the contaminated food or drinks. Bacteria can cause infection directly in the intestine or release toxin (poisonous substances) in the bloodstream to cause infections. When a person suffers food-borne diseases, he or she will show one or more of the following symptoms: fever diarrhoea vomiting dehydration stomach aches/cramps The symptoms of food-borne diseases may take several hours or days to develop because bacteria need to reproduce to sufficient numbers before they can induce serious infecti ...

Physics Tuition Singapore Secondary Science Tuition – Chemical effect – Electroplating   Chemical effect A chemical change caused by electricity is called electrolysis An electrolyte is a liquid or a solution which can conduct electricity. The electrolyte undergoes chemical change when electricity passes through it. Electrodes are electrical contacts which allows electric current to leave and to enter the electrolyte. Electrolysis is widely used in electroplating and in the extraction of metals.   Electroplating In electroplating, an object is coated with a layer of metal. The object to be coated is connected to the negative terminal of the power supply. The metal to coat an object is connected to the positive terminal of the power supply. For exampleTo coat a spoon w ...

Chemistry Tuition Singapore Secondary Science Tuition – Separating Mixtures Solid – Solid   SEPARATING MIXTURES There are physical methods which can be used to separate a mixture to obtain pure substances again. The choice for selecting a suitable physical method is determined by the nature of the mixture. Solid-solid Two different solid substances mixed together such as sand with salt or iron powder with sulfur Solid-liquid Salt solution, sugar solution Liquid-liquid Alcoholic solution, crude oil Quantity of components Sample containing minute amount of components such as food dyes, food colouring and inks   SEPARATING SOLID-SOLID MIXTURES Magnetic attraction This technique uses magnets to separate magnetic substances from a mixture. Examples of magnetic substances a ...
