Chapter 20, Problem 11A

Summary Introduction

To describe:

A hypothesis to reduce the mold spores.

Introduction:

Mold is a fungus, which can easily grow in moist and damp places. The molds are generally non-harmful, but some people may have serious allergies to mold.

Explanation of Solution

The mold grows in the region where it is moist and ill ventilated. So, in order to reduce the mold spores, the place should be kept dry and well ventilated. To test this hypothesis mold spores can be placed in two places, one which is moist and other that is dry and placed in sunlight. To maintain dry conditions, silica gels can be used.
