Process of gaseous to solid state without going in liquid state is known as reverse sublimation.

but it isn't similar to sublimation

it is just opposite of sublimation.

difference between the two lies in the initial and final State during the process of conversion..

  3. Temperature >Degree of hotness or coolness. Unit of temperature: SI Unit of measuring temperature is 'kelvin'. Most common unit is degree celsius". Values: Melting point of ice is 273.16 K or 00C. Boiling point of water is 373 K or 100 C.


  4. Conversion a) Celsius Kelvin temp in kelvin = temp in celsius + 273.16 b) Kelvin Celsius temp in celsius = temp in kelvin-273.16 Remember: 00C = 273 K.


  5. Change of states of matter Sublimation Melting aporization Solid Liquid Gas Freezing Condensation Reverse Sublimation By changing pressure or temperature.


  6. Quick Recap Solid to liquid : 1. process is melting. 2.temperature is melting point. 3. change of physical state. 4.temperature remains same. Liquid to gases : 1. process is boiling. 2.temperature is boiling point. 3. change of physical state. 4.temperature remains same.
