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
