Answer 1

Answer:

B. Temperature

Explanation:

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.
