ANSWER!!!

Mothballs in the U.S. contain high concentrations of either naphthalene or paradichlorobenzene. Both active ingredients are solid chemicals that slowly become fumes at room temperature. The fumes kill clothes moths when trapped inside sealed containers. Mothballs slowly disappear as they turn into gas and mix with the surrounding air. The time it takes a mothball to vaporize depends on many factors, including how many mothballs are present, the amount of air-flow around the mothballs, and the temperature.

You can observe mothballs disappear in cabinet?

  • Mothballs disappear because they are composed of a weak molecular structure called naphthalene or paradichlorobenzene. Mothballs change from a solid into a gas in a process called sublimation.

What do you think the reason for this?

  • Because they are composed of a weak molecular structure called naphthalene or paradichlorobenzene.

Do all substances behave like mothballs at normal conditions? Explain by citing some examples?
