Properties of Matter and their measurements
Properties of matter and their measurements The property of matter can be classified into categories physical properties and chemical properties. Physical properties - physical properties are those properties which can be measured or observed without changing the identity or the composition of a substance. Some examples of physical properties are colour, smell, melting point ,boiling point ,density etc. Chemical properties- the measurement of chemical properties requires a chemical change to occur. For example chemical properties are characteristic reactions of different substances, these include acidity or basicity, combustibility etc. Many Properties of Matter such as length, area, volume are quantitative in nature full stop any quantitative observation on measurement is represented by a number followed by units in which it is measured. For example length of a room can be represented as 6 metre, here 6 is the number and M denotes metre the unit in which...
periodic table part 1
Periodic table Part.1 (A) Prouts concept Is simply asm.com the elements are made up of hydrogen so we can say that .. Atomic weight of element= n×(Atomic weight.of one hydrogen atom) Where n= no. of hydrogen atom= 123 Drawbacks or limitations: Letter on elements discovered having atomic weight infections like chlorine atomic weight 35.5, Strontium atomic weight 87.5 and proud could not explain why this weights are instructions beasar this is a drawback. (B). Dobereiner trait rule He made groups of three elements having similar chemical properties In Dobereiner trait, atomic weight of middle element is equal to the average atomic weight of first and third element. Eg. Cl Br. I 35.5 80.0. 127 35.5+127/2 = 81.25 (C) Newland law of octaves He arrange the element in increasing order of their atomic mass and observe that properties of every 8th element was similar to the first one like in the case of musical vowe...
