CHEM 1211L Lecture Notes - Lecture 2: International System Of Units, Ampere, Thermometer
Document Summary
In chemistry domain measurements are basic in calculations that chemists make. In chemistry laboratory we can measure sample volume by different instruments such as : buret, pipet, graduated cylinder, volumetric flask. Si units are related to french system international unit. Si base units meter kilogram second ampere kelvin mole m. Prefixes used with si units symbol meaning p n u m c d k m g t. Kg=1000g g=10-3kg mg=10-3g g=1000mg ug=10-6g g=106ug: volume volume is measured by cubic meter volume = length x width x height v=mxmxm=m3 m=100cm cm=10-2m m=10dm dm=10-1m m=1000mm mm=10-3m m2=1002cm2 =104cm2 m3=1003cm3=106cm3 m2=10002mm2 =106mm2 m3=10003mm3=109mm3 m2=102dm2=100dm2 m3=103dm3=1000dm3. 1liter = 1000ml = 1000cm3 because 1ml=1cm3: temperature there are three tempreture scale, celsius, fahrenheit, kelvin to convert from celsius to fahrenheit we use this equation. F= (9/5 c) +32 to convert from fahrenheit to celsius we use this equation.
