Does the number of particles change as the substance changes its state?

Particles stay the same unless there is a chemical change whether the matter is solid, liquid or gas. ... When substances change state there is no change in mass so if 100 g of ice is melted 100g of water are formed this will boil to form 100g of steam (this is called "conservation of mass").

No. The number of particles in the substance remains the same when the state of matter changes.
