∙ 12y agobecause the air freshener substance reacts with oxygen and the chemical x is removed from the substance. after this the solid slowly dissolves over a period of time. actually it follows a sublimation process.
It disappears because it is slowly dissolving and evaporating which gives its smell off.
the ice is removed by the friction in the air , small fragments are automatically removed the solid due to highpressuregets evaporated
This process is known as sublimation (e.g. Common example is wet clothes will freeze on cold day, but the ice will disappear in a short time without melting)
Because it sublimes (changes directly from a solid to a vapor) at room temperature. naphthalene balls are vaporisable substance so they easily turn into vapor , they can turn into vapor because the intermolecular force is very weak so it easily vaporises to gas

Naphthalene or moth balls sublimate(change from a solid to a gas) so they can "disappear" without wetting the clothes.
Car fresheners are an example of sublimation because the freshener gives off a smell, which is really a gas, without becoming a liquid. (Sublimation is a solid changing directly to a gas with out going through the liquid phase)
Assuming that the solid air freshener directly becomes gaseous, the process is called sublimation.
Air fresheners contain compounds with low volatility.
The solid separates down to the molecular level - and they mix with the water molecules. We cannot see molecules with the naked eye !
The trick is to not use blocks that are affected by gravity. Sand and gravel are affected by gravity, and will fall in. So use dirt, wood, or stone. Then you will have a perfectly solid structure :)
When you open a solid air freshner, the solid slowly loses mass and volume due to sublimation. Sublimation occurs when the surface particles of a solid gain enough energy to form a gas. Since solids are closely packed together and have a definite shape and volume and gases have no definite volume, when the solid air freshner sublimates, it causes the solid to lose shape and volume to turn into gas.
Yes it's a physical change there is only a change in matter
