Study Notes

Divisibility of Matter

  • Ancient Indian and Greek Philosophers questioned the divisibility of matter.
  • The concept of Parmanu (atom) was proposed in ancient India as the smallest indivisible particle of matter.
  • Pakudha Katyayama proposed the existence of Parmanu in the 6th century BCE.
  • Maharishi Kanad elaborated the doctrine of Parmanu in the 6th century BCE.
  • Kanad believed that all matter is composed of Parmanu, which can exist individually or in combination.

The Significance of Parmanu

  • Parmanu signifies the fundamental building block of all matter.
  • Modern Atomic Theory was influenced by ancient Indian concepts like Parmanu.

Parmanu in Modern Science

  • Atoms are now known to be divisible into subatomic particles like electrons, protons, and neutrons.
  • The concept of Parmanu highlights the ancient Indian understanding of the fundamental nature of matter.

Molar Mass Calculations

  • H2O (Water): 18 g/mol (1.01 g/mol x 2 + 16.00 g/mol)
  • CO2 (Carbon Dioxide): 44.01 g/mol (12.01 g/mol + 16.00 g/mol x 2)
  • CH (Methane): 16.04 g/mol (12.01 g/mol + 1.01 g/mol x 4)

Building Blocks of Matter

  • Atoms are the fundamental building blocks of all matter, no matter how large or small.
  • Bricks are the building blocks of a huge building.
  • Sand and Soil are the building blocks of an anthill.
