### Fluid Absorption and Swelling Dimensional Changes  
The absorption of moisture implicitly leads to the volume increase of the wood. The absorption of the amount of solvent was determined, both in grams and in cm\({}^{3}\), and it was found that the highest absorbed volume was of acetone, followed by water, and

It is found that the absorption in grams is higher in the case of water, compared to acetone and white spirit, and the humidity of the samples extracted from water had the highest values (Figure 6). The moisture content, obtained mathematically, can be attributed to the fact that the samples experienced an intense xylophagous attack that caused galleries in the wood. The wooden substance was lost and was replaced by the liquid absorbed by the wood. \begin{table}

Table 2: Means obtained from the determinations for the 12-millimeter-thick sectioned samples. Figure 6: The moisture contents of the samples as a percentage, after immersion in solvents for 15 min. The results regarding the determinations of mass, volume, solvent absorption, and density, both before and after immersion of the thin specimens, can be seen in Table 2.  
The densities reached by the samples after immersion can be seen in Figure 7.  
The same methodology was applied to the samples with a thickness of 27 mm, and the results thus obtained can be seen in Table 3. Observing the results obtained in Table 3 and comparing them with those in Table 2, it can be seen that the behavior of the wood is different depending on its thickness, the type of liquid, and the length of time during which the liquid acts on the wood. Comparing the two types of samples with different thicknesses (27 mm and 12 mm), the difference in volume growth can be seen in Figure 8.

For this experiment, we wanted to report the changes regarding swelling in the tangential direction because this section produces the greatest change, according to the specialized literature [12,13]. These changes are noted in Tables 4 and 5.
