Softwoods are often derived from coniferous trees; that is, trees with needle-like leaves and whose seeds are covered in cones. Characteristics of Hardwoods. Being refractory means that they are capable of withstanding a variety of abuses like high temperatures and chemical attacks. < >. Howard (1973), when examining southern pine, found that extractive content was positively correlated with the heating value and accounted for 54% of the variation, whereas variation in the proportion of the main chemical constituents had only minor … Softwood serve various purposes; For instance many doors, windows and papers are made from softwood. thx for helping me with my science fair project!!!!!!!!!!!!!!!!!!
