  • The volatile metal compounds of copper, calcium, and strontium are generally used in fireworks to get colours.
  • This is because these metals have low ionisation enthalpies. 
  • Strontium Carbonate imparts red colour, Calcium Chloride imparts orange colour, and Copper Chloride imparts blue colour.
  • A firecracker contains a fuel charcoal, sulfur and potassium nitrate -similar to gunpowder.
  • When the firework explodes, the metal particles start oxidizing and heat is produced.
  • This heat excites the metal particles and colourful light depending on the metal is emitted.
  • Enthalpy is the total sum of the internal energy and the product of the pressure and volume of a thermodynamic system.
  • Ionization energy is the energy that is required to remove an electron from its orbit to a point where it is no longer associated with that atom
