What do solid blocks of air freshener disappear after a few weeks without a trace?

because of the chemicals that the producers use and because the smell has been spread out and of how far it was spread.

Why do solid blocks of air freshener disappear without a trace after a few weeks?
because 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.
Why does a solid air freshener disappear?
It disappears because it is slowly dissolving and evaporating which gives its smell off.
When Ice on a car windscreen will disappear as you drive along even without the heater on explain why this happen?
the ice is removed by the friction in the air , small fragments are automatically removed the solid due to highpressuregets evaporated
What is the name of the change when a substance goes directly from a solid to a liquid?
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)
How naphthalene balls sublimate?
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

Explain why naphthalene or moth balls disappear without wetting the clothes?
Naphthalene or moth balls sublimate(change from a solid to a gas) so they can "disappear" without wetting the clothes.
Is car freshener an example of sublimation?
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)
What phase change when air freshener is sprayed its container?
Assuming that the solid air freshener directly becomes gaseous, the process is called sublimation.
How does a solid air freshener lose mass and volume?
Air fresheners contain compounds with low volatility.
When a solid dissolves in a liquid it seems to disappear into it. how is it possible?
The solid separates down to the molecular level - and they mix with the water molecules. We cannot see molecules with the naked eye !
Why does a solid room air freshener lose volume and mass?
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.
How do you make a roof in minecraft without the blocks falling?
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 :)
Is solid air freshener a physical change?
Yes it's a physical change there is only a change in matter
What is the cool solid blocks that float on the asthenosphere?
Lithosphere
