Is burning of wood sublimation ? Do all solids get converted to liquid upon heating ?
Sublimation is change of state from solid to gaseous state. It is an example of physical change.
Burning of wood is a chemical change. By burning of wood, we get new compounds in form of CO2 , H2O and ashes which have different characteristics from wood.
So, burning of wood is not sublimation.
No, all the solid does not change into liquid by heating. Some may change directly to gas For example, when ammonium chloride is heated, it changes directly from the solid state into the gaseous state. Another example is camphor, which on heating changes directly from the solid state into the gaseous state.
Some solid undergo chemical change on heating as heating of wood.
