Physics Tuition Singapore Secondary Science Tuition – Electricity Heating Effect   Heating effect The conversion of energy in the heating effect of electric current: Electrical energy —> Heat energy The resistance of an electrical conductor causes the conversion of electrical energy into heat energy when electric current flows through it. The greater the resistance of the electrical conductor, the greater the amount of heat energy Different electrical conductors have different degrees of resistance. For example Nichrome has a higher resistance than copper. Therefore, nichrome is used as the heating element in a kettle. Copper Certain electrical conductors such as tungsten give out heat and light   Please contact Angie @ 96790479 or Mr Ong @ 98639633 if you need Physics T ...

Chemistry Tuition Singapore Secondary Science Tuition – SEPARATING SOLID-SOLID MIXTURES   SEPARATING SOLID-SOLID MIXTURES Magnetic attraction This technique uses magnets to separate magnetic substances from a mixture. Examples of magnetic substances are iron, steel, nickel and cobalt. For example A magnet can be used to separate iron from sulfur in a mixture of iron and sulfur.     Sublimation* It is used when a mixture contains a solid substance which sublimes upon heating. Examples of solid substances which undergo sublimation are iodine crystals, naphthalene (mothballs) and dry ice. For example Iodine crystals can be separated from salt crystals by heating the mixture until the iodine crystals sublime.   Please contact Angie @ 96790479 or Mr Ong @ 98639633 if y ...
