1 fast change occur in chemical reaction nd slow change in physical reaction.
2 reversible means the reactant can be obtained again nd in irreversible it's just opposite.
3 in chemical change : 1 change in smell ,2 change in taste etc take place.
in physical change :1 the state of matter nd 2 the temperature changes etc. .
sry for incomplete ans

THESE ALL ARE THE CHANGES THAT HAPPEN IN OUR DAILY LIVES. HERE YOU HAVE THE DIFFERENCES BETWEEN :
1. Fast change and Slow change:
Fast change: The changes that happen in short period of time are known to be Fast changes. Ex- Striking of a match.
Slow change :The changes that happen in long period of time are known to be slow changes. Ex- Ripening of fruit.
2.Reversible and Irreversible.
Reversible: The changes which can be repeated are known to be reversible changes. Examples- Tearing a paper.
Irreversible changes : The changes which cannot be repeated are known to be irreversible changes. Example - Burning of wood.
3.Chemical and physical changes.
Chemical changes :The changes which are irreversible and where a new substance is formed.Example-Rusting of iron.
Physical changes :The changes which are reversible and no new substance is formed.Example-Growth of plant.
4.Desirable and undesirable changes.
Desirable changes: The changes which is useful to the organisms and they want it to happen. Example - Cooking of food.
Undesirable changes :The which Is not useful for organisms and don't want to happen. Example - Rotting of fruits.
5.Natural changes and Man made changes.
Natural changes: The changes that occur naturally are natural changes.Ex -Climate
Man made changes :The changes that occur due to man kind are man made changes. Example -Pollution.
6.Periodic and Non periodic changes
Periodic changes: The changes that happen in particular period of time are known to be Periodic changes. Ex-Rotation.
Non periodic :The changes that happen in any time are non periodic. Ex-Cyclones.
