    Study Notes

    Dipole-Dipole Interactions

    • Dipole-Dipole interactions are a type of intermolecular force between polar molecules
    • They are attractive forces that occur when the positive end of one molecule is attracted to the negative end of another molecule

    Hammer Mills

    • Hammer mills work on the principle of impact
    • Hammer mills use rotating hammers to break down materials by impact

    Opioid Analgesic Drugs

    • Opioid analgesic drugs cause erection of the rat's tail
    • These drugs work by binding to opioid receptors in the central nervous system
    • This binding results in pain relief and a sense of euphoria

    Sodium Bicarbonate

    • Sodium bicarbonate is more commonly known as baking soda

    Spectrum

    • The spectrum is the band of coloured components of a light beam
    • It is a result of the separation of light based on its wavelength

    Caprolactone

    • Caprolactone is a synthetic polymer
    • It is used to produce a variety of products, including plastics, fibers, and coatings

    Compressed Natural Gas (CNG)

    • CNG is a common fuel for vehicles
    • It is a compressed form of natural gas

    Hugo de Vries

    • Hugo de Vries introduced the mutation theory
    • This theory explains how mutations in genes drive evolution

    Vibrational Energy

    • The absorption of infrared (IR) radiation by molecules causes changes in vibrational energy
    • Vibrational energies are the various modes in which a molecule can vibrate

    USB Flash Drive

    • A USB flash drive is an internal device used to store information

    North-East

    • The next number in the series 61, 73, 66, 78, 71 is 83

    Flax Seed

    • Lignans are components of flax seed

    Spectrophotometry

    • Spectrophotometry is a technique used to measure the absorption of radiation
    • It uses a device called a spectrophotometer

    Draughts

    • Liquid oral preparations given in single-dose containers of about 50 ml are known as draughts
    • They are used to deliver medication quickly and efficiently

    g/ml

    • Apparent bulk density is expressed in terms of g/ml
    • It is a measure of the mass of a material per unit volume

    Epsilon

    • Epsilon is not a type of radiation obtained from radioactive compounds

    Viral Vaccine

    • The small-pox vaccine is a viral vaccine
    • It contains a weakened or inactivated form of the virus

    Steroidal Glycosides

    • The compound present in Ashwagandha is steroidal glycosides
    • These compounds are known for their medicinal properties

    Tartar Emetic

    • Antimony potassium tartrate is commonly known as tartar emetic

    Flower Bud

    • Clove, a common spice, is obtained from the flower bud of the clove tree

    Eutectic

    • When camphor and menthol are added together, a eutectic mixture is formed
    • This mixture has a lower melting point than either component alone

    58 seconds

    • A train takes 58 seconds to pass a station platform that is 54 seconds long.

    Teeth

    • Enamel is a constituent of teeth
    • It provides a hard, protective outer layer for teeth

    Meter

    • The SI unit of wavelength is the meter

    Metamorphosis

    • Metamorphosis is the transformation of a larva into an adult through drastic changes
    • It is a common process in insects and amphibians

    Statistical Procedures

    • The statistical procedure to detect differences between two or more samples is called a hypothesis test
