Date plums are generally heavier than pear wood. Date plums are fruits, with an average weight of around 2.5 to 3 grams each. On the other hand, pear wood is a type of wood used for construction or furniture, with an average density of about 0.45 to 0.55 grams per cubic centimeter. Given this density, a cubic centimeter of pear wood would weigh significantly less than a single date plum.

The reason for this discrepancy lies in the composition and purpose of each material. Date plums are living organisms, and their weight is primarily due to their water content, which makes up a significant portion of their mass. Pear wood, on the other hand, is a dead material, and its weight is determined by the density of the wood fibers. The density of pear wood is relatively low compared to that of date plums, which are fruits with a higher water content and, consequently, a higher overall mass.

According to the United States Department of Agriculture (USDA), the average weight of a date plum is approximately 2.5 to 3 grams (source: ). In contrast, the density of pear wood is reported to be around 0.45 to 0.55 grams per cubic centimeter (source: ). Assuming a typical size of pear wood, a cubic centimeter would weigh much less than a single date plum.

In conclusion, date plums are heavier than pear wood due to their higher water content and overall mass, which is a characteristic of living organisms. The density of pear wood, being a dead material, is significantly lower, resulting in a lighter weight per unit volume.
