TO PROVE THAT OCCURANCE OF ATMOSPHERIC PRESSURE BY TUMBLER AND POSTCARD METHOD

Leave a Comment / Physics Practical, SCIENCE PRACTICAL /

MATERIAL REQUIREDS A glass tumbler, water, postcard THEORY The force per unit area is called pressure. The pressure exerted by atmosphere is called atmospheric pressure. The atmosphere exerts pressure about 1.013 ✖ 10 5 N/m-2 or 760 mm of Hg at Sea level. Atmospheric pressure can hold about 10 m high water column. PROCEDURE OBSERVATION […]

TO SEPARATE DIFFERENT COLOURS FROM GIVEN INK MIXTURE BY PAPER CHROMATOGRAPHY

2 Comments / Chemistry Practical, SCIENCE PRACTICAL /

MATERIAL REQUIREDS Filter paper, beaker, beaker cover, dropper, mathematical box, distilled water, alcohol, given ink mixture THEORY Chromatography is a technique that is used for separating the components of a mixture by passing it through a column or sheet of an adsorbing material. The principle of this process depends upon the fact that “the different

TO SEPARATE PURE WATER FROM COLOURED WATER BY DISTILLATION

1 Comment / Chemistry Practical, SCIENCE PRACTICAL /

MATERIAL REQUIRED Distillation apparatus, Coloured Water, Bunsen Burner, Tripod Stand , Stand with clamps THEORY Distillation is a process that relies on evaporation to purify water. Mixture of water or impure water is heated to form steam. Inorganic compounds and large non volatile organic molecules do not evaporate with the water and are left behind.
