Not necessarily.
Burning is a chemical reaction between a substance and oxygen. Sublimation is a type of physical state change produced by changes in temperature and/or pressure; it is not a chemical reaction. Sublimation is not the same as combustion.
Sublimation
sublimation.
This process is called sublimation. It occurs when a solid substance changes directly into a gas without passing through the liquid state. Sublimation is a physical change driven by the solid substance's vapor pressure exceeding the surrounding pressure.
A chemical reaction is one that changes the chemical properties of a substance. Sublimation is just going from solid to a gas and is only a change of state.
the reaction rate
Reaction Rate
rate of reaction
Sublimation is an endothermic phase transition from solid to gaseous state.
The measure is the rate of reaction.
It indicates how fast reactants become products.
The pulses on the fast laser will enable us measure the reaction time on the chemical reaction.
